Back in November of 2005, I presented an invited paper on the Windows Color System (WCS) at CIC 13 in Scottsdale, AZ. The annual IS&T/SID Color Imaging Conference is the world's premier color science conference, and draws distinguished color scientists and engineers from all over the world.
The evening session was packed, with essentially the entire conference in attendance. The presentation was very well received, and the tone of the following Q&A session was distinctly positive. It generated a lot of interest among the attendees, and I was fielding questions for the rest of the week. As it turns out, this was the first public presentation on WCS at a non-Microsoft-organized event.
The PowerPoint deck for the talk is available here: Evolution in the Microsoft Color Management Ecosystem.
