I recently had the pleasure of attending and video taping
a presentation by Graham Nash, who besides being an incredible
musician is also a reknowned (sp?) photographer and graphic artist.
there is an mp3 of an interview with Graham talking about Nash
Editions which has been a leader in digital images and bringing
back black and white . He speaks about 14 megapixel pictures.
