35mm Film: A basic Overview
35mm film photography cameras use film which is tightly wound onto a single-spool and placed inside a light sealed metal case. This case is called a film canister. The film produces 36 x 24mm negatives and is known as 35mm film. The name of 35mm is indicative of the width of the film, however, in reality, the film is a little bit smaller than 35mm: it's around 1 3/8 inches wide, or 34.9mm.
Print film also known as negative film produces a complete inversion of the picture captured, where light fields appear dark, dark areas appear light, and colors are also turned into their corresponding complementary colors.
These negatives are then developed and then projected onto photographic paper using an enalrger. During this process of making a print, The actual image's colors are restored.

Reversal film produces a real image on a translucent base. The processed film includes an accurate transcription of color, and light and tone, and requires no additional treatment. Talking about films, all films have a speed rating, which means the film's sensitivity to light.
For instance, films with a lower speed are almost insensitive to light, hence need greater exposure to it. You can get 35mm films with 50 ISO. This type of film would be good for bright light situations or where you want to use a really slow shutter speed. That's why they are called slow films. Higher speed films are usually more sensitive to light, need shorter exposures, and are referred fast films. These types of film are great for sports, street photography and low light situations. High speed film is charcterised by a higher iso grade. These days 35mm colour film can be mostly found at 400iso. Black and white films can go upto 3600 iso.
The significance of film speed, of itself, determines the abilities of a camera to suit different light conditions. For instance, if you are thinking of shooting in a low light situation, then a faster film will be a good choice.
