Ok so I have some Tmax 400 in 120, and am going to shoot it through an old Sears Tower box camera. The only setting on the thing is the diaphragm size, a crude version of aperture, and there are only two settings. I am going to be shooting it at a party at school that is themed for the 20's and I thought it be cool to tell everyone the camera is from the 20's and use it ( I know that isnt true) and later scan the negatives, but since this will be indoors, but well lit by florecent lighting I was wondering if I should push to 800 or not. I am sure others have been in this situation, and I am wondering if I could get any help. I know either way the results wont be fantastic, but I am *thinking* that it would be easier to push to 800 and if necassary fix in photoshop than to way underexpose at 400 and have to try and salvage that in photoshop. Thanks a ton in advanced guys.
