Most of my high-end clients including a number of photographers, photolabs
and museums use a color space called 'DonRGB' which is vastly superior to
either Adobe, Bruce, ColorMatch or sRGB in terms of color gamut. I designed
it about six years ago to avoid the clipping of other spaces when archiving
Ektachrome scans. I have recently expanded it in a new space called
'BestRGB' to include the added saturation of FujiChrome Velvia.
Unlike Adobe, Bruce and sRGB my spaces are all 5000K based to comply with
ICC, CIE and graphic arts standards. If you must use sRGB or Adobe, go in
and change the white point in Photoshop and save a new version with the
'D50' suffix. But prepare to lose any decent red saturation, even in Adobe.
If you want the best possible RGB color space, without the danger of illegal
CIE coordinates (as in Kodak's ROMM RGB), download the DonRGB4 and BestRGB
spaces FREE from my website at;
www.hutchcolor.com/profiles.html
Or just type in the data in Photoshop, as follows:
DonRGB4 ......
WHITE POINT:
D50 (5000K)
GAMMA:
2.20
COORDINATES:
Rx 0.6960, Ry 0.3000, Gx 0.2150, Gy 0.7650, Bx 0.1300, By 0.0350
BestRGB ......
WHITE POINT:
D50 (5000K)
GAMMA:
2.20
COORDINATES:
Rx 0.7347, Ry 0.2653, Gx 0.2150, Gy 0.7750, Bx 0.1300, By 0.0350
There is also a free Excel spreadsheet there that shows you the different
spaces on a CIEYxy diagram.
