Why are there different types of film?
Each film will have it’s own pros and cons. In general, slow films will give the best color, contrast, resolution, grain structure, and usually be less expensive. High speed films will allow you to shoot in low light or freeze the action of fast moving objects, but will have higher contrast, less intense color, and cost a bit more. Films that are slow, low ISO number, won’t allow you to get a shot in low light. They will give you the sharpest picture, and the best color, when you are in a well lit setting. In general an ISO of 100 or less is considered slow film. High speed films, high ISO number, will allow you to get a picture in low light settings, but will be more grainy and have higher contrast than the lower speed films. Films with ISO of 400 or more, are considered high speed films. 200 speed film is considered high in absolute terms but is considered slow if you are in a very low light setting. So 200 speed film is thought of as a general purpose film which will allow you more
