I have a question about how my SLR cameras exposure value "EV" function might relate to pushing film. I guess what confuses me is the .5 steps. I'm assuming that a full step is the same as one stop? The half steps must just be for a more fine adjustment right?
Where I'm going with this....My entry level SLR does not have a function to change the ISO setting for film as it reads the code on the film canister. To achieve the same affect, couldn't I simply use the camera's over or under exposure compensation feature? I.e. load 400 speed film and then set the exposure +1EV to simulate shooting this film at 200 instead of 400?
