Scenes that are light overall, such as a snow scene, can look too dark in the final photograph if you make just an overall reading or let an automatic camera make one for you. The reason is that the meter will make its usual assumption that it is pointed at a scene consisting of light, medium, and dark tones, and it will expose the film accordingly. But this will underexpose a scene that consists mostly of light tones, resulting in a too-dark final photograph. Try giving one or two stops extra exposure to such scenes.
The term high and low key refer to the dominant prevailing tones 8211; light or dark 8211; used in a picture. A high key photograph consist mostly of white and light tones and some middle tones, whereas a low key photograph is composed predominately of black and dark tones. 8230;
Infrared, photographing the unseen (or simply create very interesting) images.
Discover where a circuit board may be overheating - where hot water pipes are buried in masonry 8211; and where heat loss is occurring through a building8217;s' roof. This would be an ideal use for infrared film. However: let me quash this myth right now! You cannot, under any circumstances, photograph heat loss with an infrared film. Infrared film can see the visible spectrum and also the near infrared up to just under 1000 nanometres.
Creative photographer are always challenging conventions and looking for new ways of coming up with eye-catching images. To kick off the brand new series on Pro Techniques, Lee Frost takes a look at how to get the best out of using infrared film.
Perspective: the impression of depth. Few lenses (except for the fisheye) noticeably distort the scene they show. The perspective in a photograph-the apparent size and shape of objects and the impression of depth-is what you would see if you were standing at camera position. 8230;
View cameras come in a variety of sizes, ranging in inches from 2 1/48243; x 3 1/48243; up to 11 x 14 formats. There are larger models, but those are usually used only for special-purpose photography because of the limits imposed by their massive size and weight. The two most popular sizes are 4215;5 and 8 x 10. All monorail cameras are modular in design. These can be specifically configured in terms of bellows, monorail length, and type of back and front components to serve a wide variety of photographic needs. 8230;
The view camera is unique because its lens and back are not rigidly fixed in one position; they can be moved readily. These movements change the relationship between the film and the lens and consequently reposition the area of sharpness or alter the shape of the subject. Each movement produces a specific effect and is defined in relation to the camera8217;s neutral position. 8230;
These movements alter the position of the image-up, down or sideways with respect to the film (Fig. 50). Identical results can be achieved with the swings and tilts combined with a change in the angle of the camera bed. There are two reasons for using the risingfalling and lateral adjustments, however. 8230;
Either the lens or the back adjustments can be used to control the plane of sharp focus, whereas the shape of the image is controlled solely by the back. Both the lens and back can be adjusted when either one alone does not provide sufficient control. However, if it is necessary to control shape and the plane of sharp focus on the same photograph, the back must be used to control the shape and the lens to control the plane of sharp focus, and the back must be adjusted first. 8230;
As the bellows on the camera are extended in order to focus and magnify the image, the amount of light reaching the film decreases rapidly. To ensure an accurate exposure it is vital to compensate for this loss of light by opening the aperture in the lens or by adding more time onto the shutter speed. This can be calculated using the following method 8230;
Artificial light sources let you bring your own light with you when the sun goes down, when you photograph in a relatively dark room, or when you need just a little more light than is available naturally. Different sources produce light of different colour balances, an important factor if you are using colour films.
