135 What's the difference between film, negative film and reverse film? ! !

135 film is ordinary film. The negative is ordinary film. Why is pepper negative called negative? It is because the color of the film is reversed and negative after being developed. Generally, the colors of reverse films are positive films, that is, the colors on the negatives are basically the same. It's called reverse film and forward film.

Add color to the negative film behind the English brand, such as FUJICOLOR negative film. The reversal film changes color to chromium, such as Ektachrome (Ekta reversal film of Kodak Company). There is a simpler identification method, which is informal but effective-you can always find the words C-4 1 on the negative box or metal cassette; E-6 can always be found on the negative box. But they are all in small print, and they are not in conspicuous places. By the way, it is worth mentioning that the negative film has a large exposure latitude, and generally, the negative film within the range of more than 3 files and less than 2 files can develop good photos; However, the reversal film generally has only a tolerance of half scale and half scale, and beyond this limit, the image effect will be obviously worse.
