A fascinating debate this and I might be overlooking something fundamental here, but in an attempt to ensure I am following this correctly: Is this discussion about 8-bit images in what is referred to as 8-bit TrueColor ie that each pixel has a value described by 8 bits to represent its RGB value. If so - or if in some other case - then how can data be considered to be 'shifted' or 'hidden'? If it cannot be described in 8 bits, then surely it cannot exist within the current colour space? -- Alan Ansell aansell@... ----- Original message ----- From: CDTobie@...

Fortunately Tom Knoll did not agree. The great irony of digital image editing is that losing data can make an image look better, so much better that its hard to fathom that the process used to get there was one of tossing image data; be that tossing it out the window entirely, or tossing it through the cracks in the 8 bit per channel floor boards, where is might possibly resurface later.
