I'm trying to make old, faded genealogical documents readable using CHEAP methods. (i.e. I'm a teacher and I'm poor.) Based on my online research, IR and UV imaging might be useful depending on the type of ink used. I know that digital cameras can't see much in the UV part of the spectrum. Does the IR cutoff filter on the imaging sensor mean my EasyShare DX4900 is useless for this as well?
