Thanks Rob.

One thing that is conspicuous by its absence is any details about the pixel dimensions of the LCD panel. If I recall correctly, a 12x16inch print would produce approximately a 200ppi print. This is not enough ppi for quality to be anywhere near equal to a traditional monochrome print. Ask for the lcd array dimensions and calculate what that means in terms of dpi in the print. Anything less than about 8lp/mm(16 p/mm) means it wont be as good as a negative projected onto paper. The fact that it moves during printing only serves to blur the pixelation in the print which will also reduce the resolutoin in the print. Tim, if I'm not mistaken you are not too far from Caterham to go down to Odysey and take a look at one of these machines in action. I did a recent test of a B+W digital file having it printed on an epson wide format printer(300dpi), a laser printer(Fuji Crystal Archive paper at 254 dpi) and a typical highstreet photo LCD projection printer. The LCD print was the worst by a long way. The Laser print (www.photobox.com) was easily the best. The inkjet was good but diifferent from a silver gelatin fibre based print. I think the LCD matrix in the DeVere needs a lot more pixels in it but it really depends on your own criteria of what is "good enough". rob champagne ============================================================================ ================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there. ============================================================================================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
