device color standards? topic




right now there are at least two ICC device color standards, whereas the
purpose of ICC was device independent color
http://www.color.org

there is sRGB which is a CRT monitor color space
http://en.wikipedia.org/wiki/Srgb

there is ProPhotoRGB which is a hybrid output film color space
http://en.wikipedia.org/wiki/ProPhoto_RGB

ProPhotoRGB was probably a response by Kodak to Hewlett Packard and
Microsoft's input of sRGB to the ICC

you could probably add SWOP to this list I think
http://en.wikipedia.org/wiki/Specifi...t_Publications

an oncoming problem with sRGB is that there is no CRT output standard
any more. There is LCD, LED, Plasma, OLED, projectors, etc.

the device standard must switch to the input as opposed to the output,
if you want a device standard, use a camera sensitivity standard

such a standard would either have to be a compromise of output standards
listed above, or a CIE device independent standard, the eye, so after 20
years ICC is back to the beginning

sRGB seems to have led to advancements in scene balance and appearance
modeling, attractive color, which is the preference in most markets, so
some good has come of this

then there is "good enough" color as opposed to the education neccesary
for accurate color

but some markets do need accurate color and digital color managed
workflows have not taken hold here according to the ICC, I think
commercial photo labs and commercial prepress labs fall in this category
