Adobe have made this a "standard" for wide gamut images
On the subject of standards I find it interesting that Adobe's
ProPhotoRGB is really Eastman Kodak's ROMM RGB renamed. Did Adobe bring
anything to that working space party or just rename it so that it sounded
more like they created it?
Actually Kodak created it to be a REFERENCE Input/Output Medium Metric
- http://www.colour.org/tc8-05/Docs/colorspace/PICS2000_RIMM-ROMM.pdf
In that paper they say: -
"A new color encoding specification known as Reference
Output Medium Metric RGB (ROMM RGB) is defined. This
color encoding is intended to be used for storing,
interchanging and manipulating images that exist in a
rendered image state without imposing the gamut limitations
normally associated with device-specific color spaces.
ROMM RGB was designed to provide a large enough color
gamut to encompass most common output devices, while
simultaneously satisfying a number of other important
criteria. It is defined in a way that is tightly linked to the ICC
profile connection space (PCS) and is suitable for use as an
Adobe Photoshop™ working color space."
In a later publication, Kodak introduced ProPhotoRGB based on the above:-
http://www.scarse.org/docs/kodak/ProPhoto-PS.pdf
and said:-
"This document introduces the KODAK ProPhoto RGB
profile and describes how to use the ProPhoto RGB
profile within Photoshop v5.0...."
"To maximize the potential of these Photoshop color management
features, Eastman Kodak Company has created the ProPhoto RGB
color space for use as a Photoshop working space that is independent
of the workstation-specific, device-dependent, monitor color definitions.
The parameters of this working space have been encapsulated in
an ICC-compliant profile you can download from:
www.Kodak.com/go/colorflow."
So the facts don't seem to agree with your comments. Kodak created it to be
a standard, and renamed it and supplied it as ProPhotoRGB for use in
Photoshop.
