[QUOTE="DavidForthoffer, post: 56956, member: 9632"] Mine is set to sRGB, but not for Ken Rockwell's reason(s). Ken Rockwell does not understand color management. His claim that he understands color management because he has a color management patent (which simply concerns hardware-based matrix multiplication) is like saying he understand the General Theory of Relativity because he understand what the "equals" means in "E equals M C squared". I [I]do[/I] understand color management.

I was the lead test developer for Adobe's color management team for a number of years. The point of using Adobe RGB in your camera is not to [I]deliver[/I] images in Adobe RGB. It is to [I]capture[/I] a wider gamut than possible with sRGB. Then, using color management software you adjust the range of colors in cropped part of your image to be what you want. Then you convert that image to a color space appropriate for your delivery medium, such as sRGB for electronic images, or the color profile associated with a particular printer. The problem of using Adobe RGB is that after you adjust the range of colors, you have fewer than 256 colors per channel, which can lead to banding. You can compensate somewhat by downsampling a high resolution image into a lower resolution, but you still lose quality in one form or another. Whenever possible, I shoot and process in RAW. That gives me much greater control over adjusting color ranges while preserving 256 colors per channel. Sometimes in the field when I want to show a client some work (in progress) on my laptop (which does not have Photoshop), I will shoot in RAW+JPEG, so I can show the client that JPEG. I would only shoot Adobe RGB JPEG if I could not shoot and process in RAW. Years ago, that would have been sometimes conceivable if I had to shoot thousands of images and didn't have enough space on my memory card. But with the larger capacity of memory cards these days, I don't shoot Adobe RGB JPEG any more. Conclusion: Shoot in RAW. Set your camera's color profile to sRGB unless you are going to be delivering final product from the JPEG. [/QUOTE]
