This thread it not intended as a troll so dont flame me or rant please. I have a genuine reason for asking this question!
For the purposes of a monochrome competition that has separate digital and darkroom print sections, what would be the best way to [non destructively] tell a darkroom print from a digital print [low cost also].
In many cases the naked eye can tell but I'd rather be more scientific to be absolutely certain.
Any advice on topic appreciated.
