You should pay particular attention to this point when composing the picture. In contrast, the center of the image remains relatively realistic. As the viewer's eyes are guided towards this center, it too is a key creative element. No matter whether you are taking photos of nature, sports or landscapes, you should select your film specifically with this effect in mind. As the overlapping of image areas results in an overall reduction in contrast, you should select a film that produces a poster-like rendition.
Zoomed shots appear to have less contrast and are sometimes even too bright and rather flat.
The best remedy to this problem is the use of high-contrast films. Slow films are most suitable for this purpose. Their stronger contrast rendition gives the results the necessary impact. The ISO 50 to 100 speed class is highly practical for this purpose. These films have a finer grain.
