Looking at a color, taking the color away, then being asked to pick out that same color from a chart. Direct comparison is a different thing.... Color A is available to view while comparing it to a chart. I was taught 16 bits was just beyond the eye's ability to discriminate. Think of it as picking paint colors for your house...... Looks good in the store... looks lousy on your walls. Or trying to match a tie to a suit.... when you have the suit on, it is easy.l With the suit in the closet, it takes a few ties to get it right...... This all came from the Imaging Business in PC's. Making PC graphics chips . And from making the color palette Dacs to drive the displays. Frank Filippone red735i@earthlink.net Howdy everyone. Simple question I grew up being told that 24 bit was the photographic standard. Beyond that the eye couldn't tell the difference. But now video cards have 32 bit or more and scanners even have up to 96 bit. Is it possible to tell between 24 and higher bit rate coulour depth? What changed? Javier
