I am using my S95 to photograph text documents (both paper & microfilm) for OCR. I have already asked about the problems of how to best photograph a computer screen for microfilm, but I've been thinking about the best way to photograph text so that the text comes out clear and crisp. Here are my current thoughts, but I would like to hear what anyone with more photography experience than me has to say:
I am using a smaller # of megapixels (around 6-7MP rather than the S95's maximum, which is 10MP), so that the resulting PDF files don't kill my computer when I actually go to scroll through them
Aperture - lower (e.g. f/6.3), so that if the camera is not exactly parallel to the page, the text will remain in focus
Shutter speed - There's a tradeoff here, because libraries are generally lower-light, so I'd like to lower shutter speed increase exposure, but without a tripod, there is a chance of camera wobble
ISO - I am not really quite sure how this would affect it.
White Balance - Again, not really quite sure.
I've been experimenting with different settings on my camera, but I am just learning about photography and would like to know if anyone has any suggestions for how to best photograph text, from books or from documents, that is easy to read.
