    ISO Setting Options

    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?

    Yes, you can do that. I often did the opposite (Change the ISO to provide exposure compensation) on my first TLR which did not have that ability.

    What kind of camera do you have? If you put masking tape over the barcode you should be able to set the ISO to what ever you want.

    A full f stop in either direction represents either double or one half the exposure. The same holds true for shutter speed changes.

    Hey David!
    Are you sure yo can't overide the film setting?? Check your book for the camera. I have a Canon Elan7... the thing can be so automatic that it tells me what to take pictures of! But there is a function that allows me to overide the setting for film speed. I would imagine there is one for your camera, too! Soooo check the manual & let us all know!

    can't you just put tape over the DX coding stuff and then input the ASA manually? Sorry for my ignorance, all my cameras work just as well without batteries as they do with.

    I've got a Nikon N4004 and it does not have any sort of manual ISO setting ability. It sucks (in that way). If you tape over the DX (or use a non-DX canister) it just defaults to 100.

    Actually why not make up stickers with the DX coding you want and then put them on the canister. I am sure you can find out what the coding is and using some masking tape and a black marker should do it. Just a thought.

    That is a great idea, Eric! I have always thought that someone should just sell sheets of stickers with the coding, for poor schmucks like me. But I will have to look into whether I can just do it myself somehow.
