“Many shades of red fall outside the gamut of photographic processes,” he said. “When this happens, these reds are assigned the closest red at the edge of the gamut. The result is that dozens of reds are assigned the same colour. Because dimensionality is defined by tonal gradations, and all of these reds are represented by the same red, a three-dimensional red area will be without gradation and will appear flat.”

Is this pablum cold or hot? It is old, but is it true; valid? Does it work on you and your eye?

The trouble with the photo bbs is that they are filled with little learners. Each taking your image to their interpretation. This usually means they are more likely to discuss what the “tech” change they would make is. Since “e v e r y o n e ” uses photoshop, they discuss brush size, or layer, or perhaps the screen profile. Never getting to your photo, your idea or you.
Don’t waste your time on the boards. Spend time looking a better photographs. Look for them. The net houses thousands, it has never been easier to find good images.
One example here. Why is this good? What makes it a failure?
