Although the earliest photographic materials were sensitive only to the blue-violet end of the spectrumpartially color-corrected achromatic lenses were normally used, so that when the photographer brought the visually brightest yellow rays to a sharp focus, the visually dimmest but photographically most active violet rays would be correctly focused, too.

Photographic prints can be produced from reversal film transparencies, but positive-to-positive print materials for doing this directly e. New and improved sensitizing dyes were developed, and in the much more evenly color-sensitive Perchromo panchromatic plate was being sold Film camera the German manufacturer Perutz.

The filters used were different for the different film types. By the s, color film predominated in the consumer market, while the use of black-and-white film was increasingly confined to photojournalism and fine art photography.

The introduction of orthochromatic emulsions required the whole range of colors from yellow to blue to be brought to an adequate focus. Many photographers who did their own darkroom work preferred to go without the seeming luxury of sensitivity to red—a rare color in nature and uncommon even in man-made objects—rather than be forced to abandon the traditional red darkroom safelight and process their exposed film in complete darkness.

Effect on lens and equipment design[ edit ] Photographic lenses and equipment are designed around the film to be used.

As part of the processing, the image-bearing layer was stripped from the paper and attached to a sheet of hardened clear gelatin. There are several types of photographic film, including: The resulting transparencies or "slides" were very dark because the color filter mosaic layer absorbed most of the light passing through.

Transparencies can be reviewed with the aid of a magnifying loupe and a lightbox. The commercial availability of highly panchromatic black-and-white emulsions also accelerated the progress of practical color photography, which requires good sensitivity to all the colors of the spectrum for the red, green and blue channels of color information to all be captured with reasonable exposure times.

Red light sensitive layer; 4. Additionally, because print film must be printed to be viewed, after-the-fact corrections for imperfect exposure are possible during the printing process.

Film basics[ edit ] Layers of 35mm color film: Because they were still disproportionately sensitive to blue, the use of a yellow filter and a consequently longer exposure time were required to take full advantage of their extended sensitivity.

Most skin tones came out unnaturally dark, and uneven or freckled complexions were exaggerated. If mounted in small metal, plastic or cardboard frames for use in a slide projector or slide viewer they are commonly called slides. As a result, the relative tonal values in a scene registered roughly as they would appear if viewed through a piece of deep blue glass.

The last films of this type were discontinued in the s, but Polachrome "instant" slide film, introduced intemporarily revived the technology.

Some photographers use their knowledge of these limits to determine the optimum exposure for a photograph; for one example, see the Zone System. Most automatic cameras instead try to achieve a particular average density. The first transparent plastic roll film followed in Photographers sometimes compensated by adding in skies from separate negatives that had been exposed and processed to optimize the visibility of the clouds, by manually retouching their negatives to adjust problematic tonal values, and by heavily powdering the faces of their portrait sitters.Feb 19,  · An excellent list!

One set you missed are the cameras from ALPA of Switzerland. Although most ALPA cameras are paired with digital backs from Hasselblad, Phase One, etc.
