Oshawa Camera Club Monthly Newsletter Issue 29 - February 201 3 Time Warp! by Bhart Mistry This image above is literally a step back in time – I’m talking Analog. Many of you know that I still dabble in the black arts – yes, I still shoot “film” every now and then. The process gives me a chance to slow down and reminds me why I got into photography (and I get to use some really cool film cameras that I couldn’t afford before!) I have a few formats that are my favourite – 6x9 folders, 6x1 7 panoramic and 4x5. I’ll usually shoot and store the unprocessed film till I find time to develop them. Last weekend, I decided to set a couple of evenings aside and process a pile that had been multiplying in the fridge over the past 7 months – a stack of 4x5 sheets and a couple dozen rolls of 1 20. I think I have the best wife in the world to let me commandeer a bathroom for a whole weekend! After so many months, I couldn’t even remember what was on these, so it was always a surprise as each piece got developed. The above shot was one gem that jumped out when I pulled it out of the fixer and dropped it in the wash. I remember going out late last summer near Campbellford, the water level was low due to the hot summer, so I was able to walk out in the shallow river bed and catch the slow flowing water cascading down the tiered rock bed. There is nothing fast about shooting with a view camera as everything is manual – right from opening and setting the camera up on the tripod, analyzing the scene, mounting the lens of choice, composing the shot, focusing through the ground glass, taking the exposure readings with a light meter, loading the film holder and making the final exposure – so, yeah, you have plenty of time to think things out. I think it’s not as much a procedure as it is a ritual in making that one image. Given the 4x5 format, shooting with a wide angle lens, would have covered a lot of ground side to side, but would have also included a lot of plain looking sky as it was slightly overcast. Instead, I decided to go with a longer focal length to give me a tighter composition and concentrate mostly on one section of the waterfall. The scene had a wide range of tones and textures ranging from the soft water to the rough stone and was ideal for shooting black and white. Opting to use a slow shutter speed gave me that silky water effect on the cascades. I likely used a bit of front tilt to increase the depth of field along with the small aperture to get everything from the foreground to the back in focus. I’m guilty as anyone else in taking images from our modern DSLRs and putting in time, effort and money with software and plugins to get the film look when the solution is so simple – if you like the film look, just shoot some film! Over the next little while, I’ll go over the other shots and get them scanned in, but for now, slow down and enjoy a bit of analog history. Details: Camera: Horseman 45FA 4x5 technical field camera Lense: Nikkor 1 35mm, f3.5 Format: 4x5 sheet film Film: TMax1 00, ASA 1 00 Shutter Speed: Not noted, but likely 1 -2 seconds to blur the water Aperture: Not noted, but likely f1 6 for depth of field Mode: Manual (As if you had any other option!)

For me, personally, it was quite a busy year: an early spring made for lots of early garden work and a continuation of our outside 5-year plan; that was followed by a 3-1 /2 week trip to Norway and Ireland; back home long enough to catch our breath and begin the 201 2/1 3 OCC season before heading off again for a 2-1 /2 week fall trip to India and Dubai; finally, the 5-year plan was finished off with ripping up and replacing our entire lawn that had been infested with grubs and crabgrass despite Dr. Green’s feeble efforts. It’s a bit early, but COME ON SPRING!! The 201 2/1 3 club season saw us start off with introducing a new meeting agenda and education program that was, in large part, a response to feedback from our member survey. Emails and conversations since tell me that the changes have been received very positively and enthusiastically, so I believe we’re on the right track. Contents Page 1 - Time Warp by Bharat Mistry Page 3 - President's Musings by Leif Petersen Page 5 - Ten Lessions by Anon Page 6 - The Travelling Photographer by Brian Greenway Page 10 - First Steps Group by Bharat Mistry Page 15 - Education Program by Bill Peel Page 17 - The Nature Photographer's Journal by Norm Ullock Page 20 - Clinic Hints by Bob Bourke Let’s reflect on a few highlights from the first half of the season: - The two fall club competitions saw an average of 220 entries submitted by 47 members. Would we like to see more members participating in the competitions? Absolutely! However, considering that the attendance at meetings is approximately 65%, that’s about a 74% participation rate, so I consider that pretty good. Thanks to all who shared their photos. - During the ‘Two Members Sharing’ program, Mike Slade, Catherine Starr, Elaine Howatt and Malcolm Parr did an excellent job presenting their photographic styles and skills. I’m looking forward to hearing from more members in the 2 nd half. Norm Ullock finessed his way through an explanation of ‘Colour Settings’, a very difficult topic presented in a very understandable manner. I’m a little biased, of course, but I think that Bharat and I did a credible job presenting Photoshop and Lightroom tips, in November. - Outside guests have certainly added to our agendas. I missed Juraj Dolanjski, but I was told that he was very entertaining. Once again, we had a successful mock judging session with Rod Trider and Gord Schmidt. I’m dipping into 201 3 now, but Richard Lautens gave us a very entertaining account of his 26 year career with the Toronto Star, at our first January meeting. - The OCC kicked off our new association with CAPA (Canadian Association of Photographic Arts) by hosting their judging course, which was organized by Bill Peel, with set-up help from Sharon and Nick Janushewski. Besides being successful in terms of attendance, with 45 people from several clubs around Ontario and Quebec, including 1 0 OCC members, it was financially successful for the OCC, since we received $740 from CAPA, for our efforts. - Three years ago, Valerie Williams, the OCC President at the time, introduced the ‘President’s Award’. This discretionary award is In Focus - Issue 29 Page 3 presented to a member who the President feels has gone out of his/her way to support, contribute to and represent the club. In the past, the award was presented to Gerry Ernest and Don Wotton. Although that award was traditionally presented during the Annual Banquet, I departed from that short tradition and recognized Bharat Mistry’s many contributions to the OCC, during the December Members’ Night. Several other activities have contributed to an excellent first half – outings organized by GJ Baylon, bowling night organized by Elizabeth Borysewicz, Members’ Night with team and members’ photo essays, etc. Last month I sent an email to all members with a brief outline of our plans for a weekend event aimed at recognizing the OCC’s long list of activities and contribution to the community and giving the members’, and very likely other club members, an opportunity to learn from some well known photographers. If the Planning Committee and Executive Committee feel that this would be a financially feasible venture, it will likely be held in April or May, 201 4. Part of that analysis will depend on whether our members’ will participate, which is something we can’t just take a guess at. In my email, I asked you to let me know if you would consider attending such an event; unfortunately, I’ve heard back from only 1 4 members! We need your feedback! Looking into the 2 nd half, we have a lot to look forward to: - Of course, - It’s competition season – GTCCC, the Annual Club Competition (ACC) and CAPA. They all seem to come due around the same time, so this can be a challenge. - The annual Spring Salon will be held in May once again. Rather than holding the Salon on 3 consecutive evenings, we’re planning for a Friday evening, Saturday afternoon and Saturday evening. More to come on that. 75 th Anniversary Planning Committee has been meeting to develop a program to celebrate this milestone, which will, for the most part, take place during the 201 3/1 4 club season. - The our regular meetings will bring us more members sharing, speakers such as Boris Spremo, on February 1 3th, more team essays, more software tips from Bharat and I and, of course, seeing your images on the competition results evening. - Last, but not least, I plan to win LottoMax this year so that I can carry through with my commitment to build a new, permanent facility/gallery for the OCC. Of course, it’ll also house Bonnie’s yoga studio. The only catch is that it has to be a minimum of $23 million! I’ll see you at the next meeting and, as always, don’t hesitate to give me your questions and comments.

Steady As She Goes. When hand-holding a lens make sure that at a minimum the shutter speed is the reciprocal of the size of the lens (e.g. 200mm lens, shoot at 1 /200 sec., 400mm lens, shoot at 1 /400 sec.) 2. Trade-offs. The larger the number (e.g. f22 vs. f5.6), the greater the depth of field. While using a smaller f-stop provides more light, in the end it may not be worth it if the image lacks depth of field. Similarly, a slower shutter speed provides more light, but if the image is blurred, it is just another image to be deleted. Try various combinations to see what works in individual situations. 3. Size. Depending upon subject matter, size of lens often matters (wide angle or telephoto), but quality of ‘glass’ always does. 4. $$$ . Treat cameras and lenses with care as they can be very, very expensive to repair and it may take considerable time to have repairs completed should parts need to be ordered from offshore. 5. Home Sweet Home. While it is wonderful to have the chance to photograph in new venues, don’t overlook nearby, everyday opportunities. 6. Enlightenment. Morning and evening are some of the best times of day to photograph as the light is wonderful and the wind in down, which is of particular benefit when undertaking macro-photography. 7. Silhouette. As a rule, when possible, stand with your shadow toward the image being photographed or, in other words, with the light source behind the camera. However, there are times when rules are meant to be broken. Experiment. 8. Preparation. Ideally, check out in advance the subject to be photographed. What is the best time of day to shoot? What behaviour can be expected from wildlife? What time does the parade start? 9. Patience. When possible, take time to capture the image envisaged. What is the optimum shutter speed and aperture? Let events unfold. 1 0. Re-charge. Make sure batteries are recharged and that snacks for the photographer are readily available. In Focus - Issue 29 Page 5 Putting the ‘Travel’ in Travel Photography Traveling seven hours in muggy and dusty conditions over very poor roads our van finally reached our destination the beautiful Vieng Vang, Laos. The hotel was modern and the evening view from the balcony was simply gorgeous. Typically tourist-like we raced to the balcony with our cameras, blown away with the view and started making “snaps, myself included. All our creativity disappeared and probably most of us ended up with pretty representational photographs identical to everyone else who has stepped out onto that hotel balcony for the first time. “But isn’t this Travel Photography?” A record of the fantastic places that you traveled to, the people you’ve met, and all the other details of your experience such as the food and daily life. In many ways the answer is yes, of course it is. However, Travel Photography is a genre of photography that like landscape, portraiture, Street, Wildlife, or Black and White can identified as being separate and identifiable. Good travel photographs should be as well constructed and complex as any other image created in the other genres. Also, like the other genres, there are always constraints, in the case of travel photography most times you don’t have the luxury to hang around for days at time to get the perfect weather and light conditions as someone who is serious about a particular landscape will often do. How do they make those incredible night shots in Hong Kong? For the two days we stayed all we had was fog and smog and did not even bother with a trip to the Peak. Given the constraints of weather and timing and the temptation to click at anything that is different and wonderful what makes for good Travel Photography? Essentially it is all about conveying rich context and story Possibly there are three areas that set Travel Photography apart from other genres of images. Firstly, by specific intent there has to be a subject that is fairly clear and understood but importantly be also part of a larger subject. Travel images have, by conscious intent contain what Michael Freeman calls “layers of subject.” (The Photographer’s Mind, Focal Press, 2011 ). Other genres may or may not have definable subjects where such things as mood, colour, texture, or shape are more in play. Secondly, Travel images have a sense of place. In a landscape for instance you could place people doing an activity and this also provides a sense of scale. This is often difficult to do in travel photography where a single image cannot represent the meaning or feel of a place so a series of images, like vignettes, can convey a mood, passage of time, purpose or activity. The final area which is particular to Travel Photography ( but certainly not exclusive to it) is often referred to as “seizing the moment”. More than any other genre anticipation and fast reaction are required to capture something unique around you which is happening in the moment. You need patience, planning and lots of luck to capture a moment in time that may never be repeated. A few examples of these three elements: layers of subject, sense of place and seizing a moment. My first shot at this “meat market” on Route 1 3, Laos was an immediate “record” of what was for sale -a reflection of personal cultural shock. A In Focus - Issue 29 Page 6 clear subject rats, but no real context to explain their presence. Stepping back to include the women broadens the “layers of subject” to include more ideas. Obviously these rats and eels are for human consumption on sale in a market. Do you like your rat fresh or dried? This image of the woman with a basket from the Bac Ha market, North Vietnam brings together a layer of subjects - the market, a shopper, meat selling, and the cultural heritage in the dress of the H’mong women. A close up of just the woman would have been interesting but not a “travel” image as such. An image of the fisherman as a subject without any background context has less impact and information than when same fisherman is included as part of the unique landscape of Laos. The ‘subjects’ are now fishing, landscape, and weather. Conveying a “sense of place” tries to capture for the viewer the meaning and experience of the destination through images that can reveal what was this place was like in the past (eg. a ghost town ) or a sense of what is going on at present in the daily lives of the people. In this image of a food stall in the Bac Ha market, Lau Cai province, Northern Vietnam there In Focus - Issue 29 Page 7 is much going on. The weekly market is not just a central place for buying and selling but is also for meeting friends, catching up on gossip, having a meal, re-affirming relationships or learning about new things and changes in the area. This image contains a lot about what the weekly market means to the local community. At the Can Cau, a massive rural market trading in water buffalo, horses and birds is quite extensive. A panoramic image gives a sense of place (size, landscape, colour) by putting the buffalo market in the context of the landscape and also by including the woman to provide a sense of scale to the subject. Again, this image from Ha Long Bay is given some sense of place with the inclusion of the boat and kayakers. Seizing the moment is a skill that maybe the hardest to master as most street photographers will attest. Not only do you have to anticipate what might happen, but also be prepared in advance of what you want to achieve and that your camera settings are appropriate to the situation and in place too. The rewards, however, can be high. Patience and waiting are pre-requisite skills, but local knowledge is crucial too. We knew that monks in Luang Prabang awoke around 5 am for prayers, followed by great Temple drums signaling the beginning of their morning walk through the city to receive alms from the local citizens. The time of their walks is never precise. However, our local guide knew of a quieter intersection (meaning fewer tourists) where we were more likely to see monks coming from different directions due to Temple locations and thereby have more than one opportunity for photographs. By 5 am we were in place and were able to capture some good images. But many times the opportunities are not anticipated but with good luck and planned “best guess” camera settings images can happen that become great travel images. In Focus - Issue 29 Page 8 Some examples: In Focus - Issue 29 Page 9 Meet some of our newest club members. This month, we have a few more new members that I would like to introduce. Tony Whillans Tony is the proud father of three wonderful kids who have all graduated from University and in his words; he has been married to the same outstanding woman for 34+ years. Now that the kids are independent he says he has the time and financial funds to support all of his hobbies. Tony and his wife Cheryl enjoy travelling. Tony is a certified Advanced Scuba Diver with over 38 years of experience and likes to combine travel, scuba diving and his passion for photography. Tony enjoys taking pictures of everything and anything. Tony can thank a fellow OCC member and neighbour of 26 years — Ron Siblock for introducing him to the OCC, reintroducing him to photography, by hanging up his old 35mm AE1 and for helping him spend his kids inheritance on new Digital SLR Camera’s, lenses and photography accessories.

Really-Quick Lesson of the Month: EXPOSURE I’ll see how this feature goes – it’ll be a quick and dirty explanation in 10 paragraphs or less. This month, achieving the perfect exposure. Exposure decisions will depend on each situation and there are basically three elements that factor in – ISO, Aperture and Shutter speed . All of them must be considered together in setting your exposure. Underexposed images will be dark, flat and lack detail in the shadows. Overexposed images will overly bright, hot and have blown out highlights. Let’s see how the three elements relate to each other and what effects they have on your final image. ISO: This controls the light sensitivity of your camera. A low ISO setting requires more light for your exposure In Focus - Issue 29 Page 13 which works great in bright lit situations and results in images with minimal noise/grain. A high ISO setting requires less light for a good exposure which is well suited for low light situations but the image may suffer with having high noise. Aperture (Av): The aperture affects your exposure by controlling the amount of light entering through the lens. (Note: all those aperture numbers on your lens are fractions of 1, so a setting of f2.8 is a bigger aperture compared to a setting of f16). Therefore, the bigger the aperture (eg. f2.8), the more light reaches your sensor, the faster shutter speed you can use. Using a smaller aperture (eg. f22), lets in less light, so you need to use a longer shutter speed. You can also compensate, by adjusting your ISO up or down to balance your use of shutter speed. The aperture setting also affects your depth of field which I will cover in a future article. Shutter Speed (Tv): The shutter speed effects your exposure by controlling how long the sensor is exposed to light. (Note again: those shutter speed numbers on your camera are also in fractions of 1, so for example. a setting of 4000 = 1/4000 of a second, setting of 4 = 1/4 second). This is how long the shutter in your camera stays open. In order to use a faster shutter speed, you would have to use a larger aperture and possible increase your ISO sensitivity. So getting the perfect exposure, you’ll have to consider the current situation and factor in how ISO, Aperture and Shutter speed settings will affect your picture – by now, you may have realized changing one will affect the other two and it will all depend on how much light you have to work with at that time. Let’s go over a few examples: Example 1 – Action Image: To freeze the action, whether shooting sports or birds in flight, you want to use a fast shutter speed. If you have enough light, such as outdoors on a sunny day, you may be able to use a low ISO and a small aperture. But shooting in low light such as an indoor arena, in order to use a high shutter speed, you would have to use a wider aperture and if that still isn’t enough, increase your ISO until you get the action stopping shutter speed that you need. Your solution could be: Fast shutter speed (1 /2000s), wider aperture (f4) and/or high ISO (iso1 600). Example 2 – Landscape Image: In general, most landscapes are static with very little movement in the scene (except eg. a windy day, or crashing waves, etc.) and your main goal is getting everything in the scene sharp front to back (depth of field) so you would likely shoot at a smaller aperture – f1 6 to f22. But since that limits the amount of light entering the lens, you compensate by using a longer shutter speed. You could increase your ISO to give you a faster shutter speed, but then you end up introducing noise in your scene. Your solution could be: Small aperture (f1 6), low ISO (iso200), longer Shutter speed (1 /1 25s) and/or using a Tripod if you need a longer shutter speed if you can’t hand hold. Example 3 – Studio Portraits/Product Image: In this situation, you have control of the lights, whether using flash or studio lights, you have the option to supply the quantity and quality of light – this gives you the freedom to use settings that best suit your subject. Your shutter speed will be limited to your maximum sync speed of your camera – this is the fastest speed you can use with a flash or studio light eg. 1 /60 to 1 /250 of a second depending on your camera model. But, since you have control of the light, you can use a low ISO and whatever aperture that suits the situation. Your solution could be: Set Shutter speed (1 /200), low ISO(iso1 00), variable Aperture (f1 .8 – f1 6), Variable output light source. I’ve just touched briefly on the subject to give you an idea on the basics here to show you how ISO, Aperture and Shutter speed effect your exposure and what compromises you have to make. Once you understand the above, you can get creative in your photography by breaking some of the rules such as using a slow shutter speed for action to show motion blur, or using really, really, long shutter speed in landscapes to soften movement, or wide aperture for a shallow depth of field to isolate a subject – it all depends on how you want the scene to look. I’ve got a few topics in mind for future Quick Lessons, but if you have anything that you would like me to cover, drop me an email with a suggestion. Cheers, Bharat. In Focus - Issue 29 Page 14 The normal “winter blues” will no doubt be in full bloom come February. What better way to tackle such moods is to do exactly what our competition director Randy did recently. (Ok...before Christmas) He got out in the cold, managed his snow settings, took a drive and captured some amazing images. His effort reminded me of educational value of learning “how” to shoot an image in less than favorable conditions. It also encouraged me to look at winter in a “new light”. Randy took his images and then “played with” them in software packages to achieve his desired effect. What a splendid effort. Our special guest on February 1 3th will be Boris Spremo. When I was able to contact him and ask him to present he mentioned that he uses only slides to share his “craft.” Picture-of-the-Month Award. During his 37-year career, his assignments have taken him around the world covering wars, famine, politics and celebrities. He will honor us with his images - certainly an evening we will never forget. Spremo has had many exhibitions of his photographs and Boris was born in the former Yugoslavia and immigrated to is a sought after speaker by photography classes at Canada in 1 957. During his career he won over 280 colleges in Canada and the U.S. He has been interviewed national and international awards for photography. He was by numerous radio and television talk shows and starred in the first Canadian to win a Gold Medal in the World press a TV commercial for EverReady Batteries. Boris lives in Photo Competition in the Hague. He is the recipient of Toronto with his wife and has four grown daughters. four National Newspaper Awards, 1 8 Canadian Press In Focus - Issue 29 Page 15 No doubt you may have seen some of the above images to “wet” your appetite. Thanks to Randy for co-ordinating the clinics this year. Bill Peel Boris has waived his normal appearance fee in recognition Educational Director of small clubs like ours where he knows he will find those Oshawa Camera Club who want to learn from his work. February 27th will mark the end of the clinic competitions for the year with Randy hoping that Clinic 4 entries will top the previous clinics. Please make an effort to share your images with us and learn from each other. In Focus - Issue 29 Page 16 Making Panorama Scapes Most photographers often find themselves looking at a landscape, seascape or cityscape and what their eyes see from the left to right horizon is a magnificent vista. But when they see it through the camera viewfinder it doesn't look so special. If only we had a lens that could take in the same geography that our eyes can see. Well there are a few lenses that can see wider than most lens that we walk around with but they are usually quite expensive. So what a lot of us do is take several single shots with a 24 - 200 mm lens then use post processing software to stitch the single shots into one image and end up with say a 1 8 inch by 48 inch image, or whatever size you want it to be. When taking shots for a panorama you can also put your camera in the portrait position to increase the vertical height of your final image. Making single shots for a panorama (pano) is not a difficult process to do but let's look at some things we can do to improve our chances of getting a better panorama image. There are three components to making a pano correctly: one is getting the exposure and depth of field correct on the single shots that will make up the pano image; second is getting the single shots geometrically correct and third is the post processing creation of the pano image itself. shooters) and pick the aperture you want to get the desired depth of field and see what shutter speed the camera sets. Then switch to manual mode and set the same shutter and aperture values. Now with your camera in static focus mode press your shutter button half way down so the camera focuses on your landscape. Release the shutter button and switch the lens / camera to manual focus mode. Now you are ready to take your single shots and they will all have the same exposure and depth of field so when they get stitched together the single image will look like it was one shot. Getting Things Geometrically correct or Finding the Nodal Point I hear some photographers talk about shooting multiple shots to make a pano by hand holding their camera and others that just put their camera on a tripod and shoot away. They say Photoshop or other pano software just blends their shots together and they get a pano. Well I am sure this might work sometimes and even if it does you are likely getting a pano using less of your single shots than you might otherwise get. This is even more true if you put your camera in portrait position on your tripod vs landscape position. Doing it handheld or without finding the nodal point will often give you broken lines in your pano where things don't quite line up. So let's look at these three components one at a time. To illustrate what happens, let me use an example of taking a compass, like the one you used in geometry class Exposure and Depth of Field in school, to draw a circle. To use this compass we would stick the sharp point into paper, then decide on the radius If we use any automatic camera mode to take single shots of our curve, then use the pencil end to draw a curve, let's that will become a panorama a couple of things will say 6 inches long. You now have a clean smooth curve happen and none of them good things. Each of your drawn because the nodal point was the pointed end of the single images will very likely have a different exposure and compass and therefore eliminated any parallax errors. quite possibly a different depth of field. This will happen Now take a pencil and divide the 6 inch curve into 6 one because you are covering a wide area and your camera inch pieces by drawing a perpendicular line at each inch light meter will meter on different objects in each frame mark along the curve, imagine you now have 6 single and create a different aperture in each shot. The different pictures (represented by each of the 1 inch curved aperture will give you a change in depth of field. When you portions) to make your pano. stitch shots together to create your pano your individual frames may have a different color of sky and/or trees with I hope I have not lost you yet. Now try doing the compass others that are sharp where all is in focus or a frame with exercise again, in your mind, without sticking the compass some components out of focus. When this happens, you sharp point into the paper and imagine the mess you will are done and the only tool that can help you is the little have trying to draw a curve as clean and smooth as the icon that looks like a trash can. one above. When you try to stitch your pano without knowing the nodal point of your camera / lens you are To avoid this you should set your camera in manual mode drawing the curve without the point stuck in the paper, before you take your first single frame shot. If you prefer, good luck! put your camera in Aperture priority (Av for Canon In Focus - Issue 29 Page 17 Each camera or in the case of SLRs the lens, has a unique nodal point location. It in fact may be in a different spot for a zoom lens depending on the focal length you use. If you just plunk your camera on a tripod in the landscape position you may get lucky and be fairly close to using the nodal point. But if you are using a ball head and you switch to the portrait position then each shot will be using a different rotation point and you will are not likely to be successful in creating a pano without using the nodal point So how does one find their lens' nodal point or if you are Our willing test targets are set firmly (they're taped down!) on a table. using a P&S camera the bodies' nodal point? Well first Initially, they there are a couple of pieces of hardware that will help should line up you. One is an L bracket for your SLR body. They are perfectly while about $1 20 - the one I use is the JOBU L bracket but Kirk your camera is and Really Right Stuff also make them. The second piece pointed straight is a nodal slider. I use the JOBU Surefoot clamp plate ahead. One is which is about $89. very near; the other about a Now I have borrowed some images from a Professional meter farther Photographer, Dave Watts who shows how to find the away. The rear nodal point of your lens. If you have a P&S camera it target should should still work. It is quite a simple process and although be propped up one inch higher, so you can see both in it make look complicated, it will likely take you about 5 the viewfinder. Beer bottles would work as targets. minutes to do. F i n d i n g you r Len s ' N od al P oi n t To eliminate the possibility of parallax errors (things not lining up properly) when stitching individual frames into panoramas, it is necessary to calibrate your panoramic head for the lenses and focal lengths you frequently use. Loosen the lock on the PCL-II panning clamp and swing the upper rig left and right noting the alignment of both the front and rear targets. In this case the slide is too far back. The bad alignment is caused by parallax error (what In this example Dave will calibrate a Really Right Stuff MPR-CLII nodal slider for a Canon 1 0-22 lens at 22mm in portrait orientation for use with the RRS L-bracket, and PCL-II panning clamp atop a BH-40 ballhead. The basics described here should apply no matter what equipment you use. I should mention this tutorial is meant as a guide for single-row panoramas. Note this procedure will likely be accurate only for the lens and focal length your are using during the calibration. we're trying to avoid). Note how the rear target seems to move left and right of the front target. Let's try another slide position... M ake s u re th e h ead i s l evel . First, place a couple of test targets in front of the lens and adjust the slider forwards and backwards using trial and error to eliminate parallax. In Focus - Issue 29 Page 18 This isn't good either. The nodal slide is too far forward and we have the opposite problem. See how the rear target moves inside the front target Success! No parallax error here. This setting is a winner. The front and back targets line up exactly no matter which way we swing the rig. Write this setting down somewhere. The location on your lens above the centre on your ballhead is the nodal point for this lens at this focal length. Make a note on a label and put it with the nodal slide, indicate camera body, lens and focal length for future use. You should do this procedure for each lens and focal length you may want to use for making panoramas. Using these techniques will improve your success making panoramic images. If you follow the simple instructions discussed in this article the entire process will become second nature to you very quickly. I will look forward to seeing some of your results. In Focus - Issue 29 Page 19 The Value of Positive Critiques – A Lesson in Judgment Not everyone is comfortable with subjecting their work for suggestions or critiques. Some people are averse to inviting comments while others are confident in their own judgment. Still others who seek critiques might simply seek either validation or flattery. None of these approaches however take full advantage of the benefits that can be learned from good positive critiques. A positive critique, done well, will offer suggestions for improvement and not simply pick out weaknesses. Quote: Flatter me, and I may not believe you. Criticize me, and I may not like you. Ignore me, and I may not forgive you. Encourage me, and I will not forget you. -William Arthur Ward Some time ago the OCC Newsletter (March 2011 ), carried an article titled “Maker’s Blinders”. This discussed a condition where photographers, the makers, look at their own images with a filtered view. The ‘maker’s eye’ can be unconsciously predisposed to focus on certain favourite features in an image while remaining less sensitive to some other things. Independent viewers who do not have the same mind filter will likely not see the image in quite the same way. They might perceive say a different-thanintended mood or be sensitive to certain features that escaped the attention of the maker. I turned to some friends and sought feedback. I respected the opinion of these friends as being able to make good independent photo critiques. They did not disappoint. Each gave me some great feedback. The comments however were all somewhat different. Where each commenter recognized the positive aspects of the image, they, at the same time picked up on some different things and suggested different ways for the image might show better. All comments were honest and valid. I had entertained some changes similar to the suggestions however I had not chosen to work them into the draft. Some of the comments confirmed that I was indeed influenced by ‘Maker’s Blinders’. This had not been a drastic oversight but, none the less, I had not effectively dealt with some subtle but important aspects of the image. Some additional rework was needed. As of this writing I’m working on a few versions of the image. I’m confident the input by the others will guide my decision on how to present the image in an even better way. It remains unknown however if I will actually be successful in creating an image with as much universal appeal as I initially hoped for. Critiques can be revealing. If you have not sought this type of positive feedback you might be surprised at how others perceive your images in different ways. I This situation was reinforced recently when I had a new encourage everyone to seek feedback from others at least image that I believed could have potential. The shot occasionally. It is a good exercise to see how your selfhowever presented a challenge. It was a rather candid critique judgment might, to some degree, be influenced by and unplanned shot but it did capture a facial expression ‘Makers Blinders’. This situation is a recognized but that was interesting. It would need perhaps some creative unconscious cogitative process that is summed up by the processing to feature the look in way that presented it in a following: more compelling way. I took an initial stab at the processing and came up with a draft version that was a big “. everything that we perceive is filtered through our improvement. I still however had reservations that it was minds, and our minds are filled with unique and personal not approaching its full potential. You should understand memories and emotions, so each of our minds perceives the image featured a personal subject but I was interested the world differently”. (author unknown) in crafting it so it might appeal to a wider audience. Often subjects with a personal interest do not translate well to others. I felt I needed a second opinion.
