| Film and Printing
I take slides (transparencies) rather than print film for a number of reasons. The positive image is viewable instantly, can be projected for viewing by large audiences, can still be used to produce prints, and in the wonderful world of club competitions and photographic exhibitions gives me the choice of entering either print or slide classes. I have tried a number of films but I have settled on Fujichrome Provia100 Professional film, a fine-grained 100 ASA slide film that gives me a good colour balance. I bulk-load my film cassettes from 30m rolls and I develop the exposed films myself using Photocolor Chrome 6 chemicals. I do this as soon as I can after taking the pictures, as I am usually impatient to see the results of my efforts - and if for some reason the results are disappointing, I may have a chance to try again. I have to say that I prefer prints to slides as there is something very satisfying in holding a successfully printed and mounted photograph. Until recently I produced 16"x12" Cibachrome (now Ilfochrome) prints on low-contrast, high-gloss paper and mount them on 20"x16" mounting boards. Now I am progressing (darkroom purists may not agree with my choice of word!) to digital imaging and output using a PC. A section on the "digital darkroom" can be found below. I take my photographs in two distinct environments. The first is in outdoors in the natural habitat, a photographic environment which is natural (not surprisingly) but difficult to control. The other is indoors in what could be considered a 'studio' environment, which is easier to control but more difficult to make appear natural. Some technical explanation is needed here. Photography involves the recording of light (the image) on a photosensitive surface (in my case, slide film). Leaving aside such minor considerations as subject and composition, the key to a successful picture is therefore control of the light reaching the film. This is done by controlling a number of separate but related elements:
The amount of light reaching the film will be the same using a large aperture and fast shutter speed as using a small aperture and slow shutter speed. The choice of which combination to use is based on a number of factors, which, in close-up photography in particular, can make life difficult. The slower the shutter speed the more chance there is of a blurred picture due to movement of either the subject or the camera, so faster is better. The wider the aperture the smaller the depth of field (the distance between the closest and furthest in-focus points) so a small aperture is best for a sharp picture. To achieve the ideal of a fast shutter speed with a small aperture we need plenty of available light, which means either bright natural daylight or artificial flash light. The natural environment There is not a great deal more to say, technically, about photographing subjects in their natural environment. It requires patience (lots of patience!) and a fair degree of luck. A photographic 'safari' is like any other - you must know where your subject is likely to be found, but when you get there you may be disappointed. I have to confess that I do not have the patience of the more successful nature photographers who may spend a day or more in hiding at their chosen spot while they wait for their subject to arrive. I prefer to pick an area and then move around it, photographing whatever of interest happens to cross my path. Sometimes I am lucky, at other times not. Flower photographs are reasonably easy to compose, the only real problems being the limited depth of field and any movement caused by air currents. When I see a likely insect subject however, I may have to 'stalk' it for some time before I can get in position to photograph it, and more often than not I do not get the picture I want. Observation is important, noting which grass stem a dragonfly keeps returning to, or which patch of flowers attracts the most bees and butterflies, so that I can position myself close by. I am convinced that butterflies in particular have a warped sense of humour. They will sit nice and still on a flower while I set up my camera and tripod, carefully composing the shot, then they will change position just as I reach for the shutter release. They can keep this up for ages! However, this adds to the challenge, and to the satisfaction I feel when I do get a successful picture. |
