Color negative film

What is the difference between "pro" and "amateur" color silver film?

Since the origins of film photography, two types of film have existed: professional and amateur films

Amateur" films

They have been formulated to be easily used by the general public, and to be developed by general public silver photo labs.

Thus, regardless of the user's skills and the state of the chemistry, acceptable results are obtained.
Included in this product line are the Kodak gold 200, Kodak Ultramax 400, Kodak 200 ColorPlus, and Fujifilm Superia 200 and Fujifilm XTRA 400.

It should be noted that even within this amateur range, there are differences in quality, since the Kodak Gold 200 and Kodak Ultramax 400 are of better quality than the Kodak Color Plus 200, which has a more important silver grain, and a less good color separation.

The "pro" films

As their name indicates, the professional silver photo films are intended above all for a public of professional photographers, photographic artists, or informed amateurs. These silver color films are more demanding, as much for their use as for their development, which requires professional silver photographic laboratories.
In the great days of silver film, each brand had its own pro range. Today, only the FUJI PRO 400H and the Kodak Portra range remain.
The Kodak range is the most complete because the films are declined in several sensitivities: Kodak portra 160, Kodak portra 400, and Kodak portra 800. The portra 160 and portra 400 are available in 35mm, film 120, film plates. The Portra 800 is only available in 35mm color negative film and 120 film.
We also find in this pro range, the Kodak Ektar 100 film which is much more saturated and contrasted. The Kodak Ektar100 is available in 35mm film, 120 film and film shots.
