Here's an interesting post by Turkish photographer, Omar Ozenir, explaining the flashing technique of controlling highlighs in a print.
A Coffeehouse in Cunda
Omar was a visitor to my blog and I followed him back to his own website, so to speak. His features posts explaining different darkroom techniques with some great illustrative pics but is in his native language.
I asked him if he could translate some posts into Englsh and I've just published the first of what I hope will become a monthly series. If you like printing under the enlarger or want to learm, it's well worth a look.
My blog, btw, is completely non-commercial. I started it to try to do my bit to spread the word about film and darkroom work. If you like it, please tell your mates. If you don't then keep it to yourself.
