Look at Photoshop CS which already has eSRG Support built into (internal
eSRG.ICC). As I have already stated some
time ago, there is a definite pull for Camera manufacturers to improve Color
Gamuts _and_ stay
backward compatible. Adobe(and Apple...) are very often ahead of what users
may already understand......<G>.
I bet, in 2 years from now at latest, the first cameras using this as a
choice will show up and
further improve fully automated Colormanagement Workflows. It4s not the
question if there may be
a better possible solution. It will happen because its logical to save
investments and fulfill industry needs.
Colormanagement is no longer geek4s teritory.
Anyone interested in experimenting with eSRG, just tag a file inside
Photoshop CS and extract it.
By the way, there is one more difference in this Adobe 2002 file version:
normal sRGB uses a perceptual intent,
eSRG uses relative colorimetric.
