Exposure adjustment?

Question:

Exposure adjustment?

OK Lets say that I am shooting an object with 200 speed film, with a shutter speed of 1/1000 and it is showing an fstop of 3.5, the maximum for my camera. How can I increase the exposure?( IE slightly Overexpose) Would I set the ISO setting to 100 or 400??

The camera doesn't have an exposure compensation dial.

Something tells me I would set the film speed ISO setting Lower to 100 to increase the exposure, but I don't understand WHY it would work!! Or If I am correct!!

Your hunch is correct. By setting the ISO at 100, the camera "thinks" that you need 1 more stop of exposure (twice the light) and will give it probably by slowing down the shutter.

Another way to do this would be to put your camera in manual mode (if it has this mode) and then you would only need to reduce your shutter speed to 1/500th.

Either way would give a 1-stop "over exposure" which may be too much. To split the difference, try an ISO of 160 or 125, or reduce your shutter speed to 1/750th, 1/600th, etc.
