Re: Copying Photos

Craig, not seen you post for a while so nice to see you back again.

Just a comment on scanner resolution vs true resolution. The Epson and AFAIK most other flat beds can scan up to 12,800 ppi @ 48 bit but that is interpolated and the actual is 6400 ppi.

While the scanner manufacturers claims about ppi is correct i.e. you do get 6400 pixels per inch it is only part of the story. Unfortunately the scanner is not actually able to resolve anywhere near this figure. Actual resolving power of these scanners runs from about 1500 ppi to a little over 2100 ppi (Epson V500, V750) if you use a test chart such as USAF.

Usually there is no advantage in scanning over 2400 as you are doing nothing more than adding pixels without adding to real resolution

Re: Copying Photos

Some Standard Copying Techniques:

Standard Copy Setup - two lights and an easel or copystand.
Lighting for Surface Texture - raking light.
Photographing Through Glass - not shooting the photographer.
Minimising Surface Reflection - cross polarising. (good for silvering)
Minimising Surface Reflection - superimposed images.
Sculpture Photography - bounced flash.
