Won't the problem be ameliorated with higher density sensors (as the fringing spreads across more buckets)? Also, of course, I look forward to the option of a purely monochrome sensor (without the colour mask - the way they used to be). That's going to be usable isn't it? - -- Stephen Holloway http://www.deepturtle.com/steve/photos
