Re: pixelation in B&W prints from 6 megapixel DSLR - unavoidable?

2004-04-07 by Dave

Hi Howard,
The Epson printer drivers really should have 300-360dpi files to print properly. 
Upsample your image to 360dpi to be safe--One resize with Photoshop bicubic is 
fine, or do it in 2-3 incremental steps with bicubic if you want.

More likely, investigate the blotchy areas in Photoshop with the eyedropper tool--is 
perhaps posterization occurring because of the levels/curves commands? If, for 
example you find the entire blotch slammed to 0,0,0 or 100% K, it may be levels/
curves that are to blame.

Enjoy your D70! I'm definitely enjoying my D60 as well.
