ISO Film Speed Guide

I am fed up with always having to search the internet for a film speed guide for when I use a film camera, so have made this guide to help me, but feel free to use yourselves if you find useful.

Types of Film Characteristics Advantages Disadvantage
100
Speed
ISO
This film has high grain and sharpness qualities. It can be used in sunny outdoor as well flash photos. Good for sunny days and flash. Best used for close-ups, landscapes and posed photographs. Not recommended for action shooting such as sporting events. Can not be used for low existing light situations without a tripod.

Very versatile film for existing light and action photography. Can be used effectively in stop action and night photography. Used by the pros in a wide variety of settings. Limited in enlargement because of the grain. However Kodak and Fuji are developing new versions to overcome the limitations.

  1. I really found this useful it inspired me to create the second sheet on aperture and shutter speed, until I have learned these principles and don’t need to rely on the notes. I would like to share the tables I made for aperture and shutter speed, but don’t see a way to attach them here. Let me know where I should send them, if you’re interested.

  2. ISO –
    My Minolta’s chip is bad. At least that’s what the camera shop said. It way under exposes my film, to my prints are black.

    I shot 800 speed film outside in broad daylight and everything was very dark.

    He said, “Instead of shooting your 800 ISO film at 800 shoot it at 200 by using a manual override.” The override is to stay in place until the roll is complete.

    What is the mathematical relationship between the amount of light required for 800 v. 200 ISO film. Is it linear or exponential?

    Hello.

    Thanks.
