At its hight of popularity, 110 film was available as colour positive and negative from many manufacturers. But things
were a little restricted as the films were only available in ISO 100 and ISO 400.
This problem is even worse these days. The only film you seem to be able to buy is ISO 200, and oddly the film is supplied
in a case set for ISO 100 film. If you have no exposure comp on your camera, the latitude of modern film will make this 1
stop difference barely noticeable.
Now if you load your own cassettes a whole new world of possibilities is opened up to you. Just think, Positive, Negative,
Ultra Fast, Slow, Infra Red, Litho, Monochrome, you name it, YOU can load it. The thing is, that to take advantage of this
you need a camera with exposure compensation, plus there are a couple of things you need to find out about your camera and
the film cases you use.
- Can your camera use ISO 100 & 400 or just 100? Lets see...
- Take the film out of the camera. (make sure you have used it up first though)
- Look into the back of the camera on the right hand side (the side that does not have the winding on gear in it)
- If you can see a small metal or plastic arm in there on the right, you have a dual speed camera.
- What speed rating is your cassette, 100 or 400? To find out....
- Take a look at the right hand end of the cassette.
- Look for a ridge that goes either all the way from to to bottom ot ust half way down.
- If it goes all the way down its an ISO 100.
- If it only goes half way its an ISO 400.
