Camera Settings on Older SLR model

On the top where you adjust the shutter speed is also adjustments for "ASA" and "DIN"

I know they effect the quality of the photographs and there are certain settings to use for certain film speeds.

I was hoping someone would know what these settings were for and how to use them. And if not maybe direct me to a website that may have this info...

Thanks for any advice given :o)

Some additional trivia about ASA, DIN and ISO. Each of these are standards organizations:
ASA = American Standards Association
DIN = Deutsche Industrie Norm
ISO = International Standards Organization
DIN is the German standards organization, although many other European countries also use them also. They establish standards for everything from nut and bolt sizes to electrical connectors, and film speeds.

Kodak, Ilford, Fuji and Agfa use a standard system for marking their boxes and cannisters with the film speed. If you look at the film speed marked on a film box, you'll see something like: ISO 200/24 with a degree symbol following it. The "200" is the ISO film speed rating (and ASA which now defers to ISO). The "24" followed by a degree symbol is the equivalent film speed under the DIN system. Next time you load your camera with film, look at both the ISO/DIN numbers on the film box/cannister and then look at both the ASA/DIN numbers your film speed dial. Both sets of numbers will match each other.
