Using films with higher ISO speed ratings. In issue #41, Canon EOS owners and other photo enthusiasts alike were shown how they could use ISO 100 film, whether color reversal or print type, for most of their photographic needs. An ISO 100 film would give very fine grain, high sharpness and color reproduction for their pictures. In certain cases, it can also be used for available and low light shooting conditions, provided that the lenses the photographer has are those incorporating fast maximum apertures. But there are also instances where the use of an ISO 100 film is not practical even if you have a number of fast aperture lenses. For example, instead of shooting at the lens' maximum aperture, you may want to shoot at the middle settings, like at f/5.6, f/8.0 or f/11, in order to have adequate depth-of-field with handhold-able shutter speeds. With an ISO 100 film, it may not be possible to do so if the light level is too low for a handhold-able shutter speed to be set with the middle aperture settings. Back in the late 70s, shooting with any film having an ISO speed rating higher than 100 would result in coarser grain, loss of sharpness, color reproduction and contrast. Things changed for the better from 1984 onwards, with the improvements made in film technologies, both slower and medium speed films were getting better in terms of color reproductions, sharpness and finer grain and manufacturers were able to use these features for the faster ISO films, resulting in products of higher image quality. Basically, there is no secret technique in using any of the higher speed films, especially those having ISO ratings of 200, 400 and 800. For films with ISO ratings of 1000, 1600 and 3200, you only have to be wary about the increase in grain size as well as some noticeable loss of sharpness, contrast and less saturated colors when compared to the other three high-speed films mentioned. Films in the ISO 200, 400 and 800 categories have utilized some of the technologies that can be found in the slower and medium speed counterparts, allowing the photographer to use them even when the lighting conditions turn bad. ISO 200 film ISO 200 film is readily available in formats ranging from 135 (35mm) to 120 (medium format). For 35mm, it is available in both color print and consumer slide versions. It is however, more limited in the professional-category of film with only one or two manufacturers specializing in them. ISO 200 film is also available in the 24mm version, known as the Advanced Photo System (APS) format.
