Dan Margulis Applied Color Theory
Image IDs: ProPhoto RGB Tests
This file accompanies Dan's 2006 analysis of gamut in
RGB workspaces. In several cases, Dan showed alternate versions of two
different images and invited viewers to decide which was best. These images
are not identified as to source within the original post, to cater to those
who prefer to compare quality without being prejudiced by knowing in
advance which is which.
The images themselves may be downloaded at
