RE: Humans (and cameras and scanners) do not have a color gamut (?)
Thank you. I love it when people are in violent agreement, but prefer a greater emphasis on agreement and less on violence. ;>) From: Andrew Rodney <andrew@digitaldog.net> Sent: Wednesday, January 08, 2020 2:02 PM To: Wayne Bretl <waynebretl@cox.net> Subject: Re: Humans (and cameras and scanners) do not have a color gamut (?)

Yes, it was in response to Wire's question about "what is gamut" (and i pointed out we're talking color gamut). Karl isn't going to state digital camera have a color gamut either. Simply repeating that "cameras do not have a color gamut" is not furthering this discussion. Please stop. No need to continue posting what Fairchild, his entire facility and Parker have stated. I agree. By definition, the raw outputs of a sensor are not colors and therefore do not represent a color gamut. Fine. I agree. That only goes to that stage of the process and offers no insight into how the sensor responses affect the gamut of the colors derived from the sensor outputs. I agree. A rendered image absolutely has a color gamut. The discussion has moved beyond the true but uninformative statement that cameras (sensors to be precise) do not have a color gamut , to considering how the gamut of sensor outputs may restrict the gamut of reported colors when converted to a color space. I didn't believe that was ever disputed nor should it be. I made a previous comment about scanners, and the resulting color gamut from a profile and I equally believe we can examine the color gamut of a scanned image in something like ColorThink Pro. I've done this often. If anyone here is suggesting the results from a digital camera (a rendered image in a RGB color space) or a scanner has no color gamut, I missed that and I don't agree. I would add the further note that sometimes the sensor gamut is the limiting factor on the final color output, and sometimes the color space (e.g. sRGB) is the limiting factor. Absolutely agree.
