- Thread-topic: Blend RGB Colors Using Gamma
In the Color Settings dialog box, under advanced¹, there is an option
called ³Blend RGB Colors Using Gamma² which allows you to specify a gamma.
The help on this option reads:
Blend RGB Colors Using Gamma Controls how RGB colors blend together to
produce composite data (for example, when you blend or paint layers using
Normal mode). When the option is selected, RGB colors are blended in the
color space corresponding to the specified gamma. A gamma of 1.00 is
considered ³colorimetrically correct² and should result in the fewest edge
artifacts. When the option is deselected, RGB colors are blended directly in
the document¹s color space.
My question for the group is whether anyone has experience with this control
and if so, have you found it to be useful? As I am reproducing artwork, one
of my goals is colorimetric accuracy so based on the help text, it sounds
like something I would want to use. However, after experimenting with it, I
can¹t really see any differences with and without it selected. The two color
spaces I would normally be color correcting in are ProPhoto RGB and Adobe
RGB (1998).
Thanks in advance...
