Re: filmscanners: To clean/wash old negatives on glass ?



Ezio: I will also be checking with some museum types I know... meanwhile my
suggestion is to NOT CLEAN the negs... leave them alone for now... if you have a
darkroom, make paper contact prints from them.... and work with those until you
get more info on how to deal with your glass plates... you could also scan them
and do your retouching in PhotoShop... but DO NOT try to clean them until you
have them checked by an expert in photographic preservation...
