Sony sensors with low read noise

I heard that Ansel Adams can pop up 15-16 stops DR from black and white films with his special post-processing techniques. <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/tongue.gif' class='bbc_emoticon' alt='Tongue' />

Using Zone System techniques it is possible to get 15-16 stops recorded at about 10 stops (or less) on film, and printed in about 5 stops on a print.



From that POV it is possible to get 15-16 stops in print, but all it means that one can compress the tonal scale enough to display fully within 5 stops. In a way, one could see this as single shot HDR <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='Big Grin' />. Not entirely, but close enough... <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='Big Grin' />. And this works well in B&W, not so with colour negatives or slides.



Other than that, Ansel Adams always did a lot of burning and dodging too, which is also why no two of his prints of the same negative are exactly the same. And essentially, one could see burning and dodging as a localized HDR technique <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='Big Grin' />.



BTW, burning and dodging is something I do a lot to this day, even with digital.



Kind regards, Wim
