For those who want to take pictures at full aperture, iso100 is still quite common, more convenient than iso400, especially using a large aperture such as f / 0.95 or f / 1.4. And iso100 is indeed much better in resolution than iso400 film.
Rollei prx’s film base is very flat, and it can be scanned directly after drying, which I personally like very much.
The charm of film photography is that you can choose a variety of films, all of which have a variety of different tones, grains, contrasts.
A lot of entry film will enhance the contrast, even if you are filming for the first time, it is easy to get good films. Germans have always been more stereotyped and do not like to please users. The Rollei rpx 400 should be considered the product of this concept.
