[QUOTE="Horoscope Fish, post: 662058, member: 13090"] I mention ProPhoto because raw files have no color-gamut. Part of the raw conversion process is the assigning of a specific color-gamut to the image file (the .TIFF, .PNG, .JPG what have you). It may be the user who chooses a particular gamut, or the software may assign the color gamut by default, but a color space IS assigned during the conversion process. Remember: raw files are NOT actual images, they're [I]data[/I] files used to [I]create[/I] images. It's the raw converter that uses the (raw) data and creates an image from it. The ability to use sRGB or Adobe RGB in-camera only applies only to JPG's; because JPG's are image files and image files must have a color gamut assigned to them. Now raw files do have a tiny .jpg embedded in them and that file does need a color gamut assigned to it which the camera does based on the menu option you've chosen, just as it does to every other .JPG you camera creates. But again, that setting has no bearing on raw files. Zero effect. For long time I shot raw, processed in ProPhoto and saved a full resolution .TIFF as my archived, finished product. Only if I needed to print or publish to the web would I convert (downgrade) the (ProPhoto gamut) .TIFF to a .JPG using sRGB. My thinking was, and still is, it's easy to downgrade from a wider gamut like ProPhoto, to a lesser gamut like Adobe RGB or sRGB, but you can't "up-convert" an image file with lesser gamut back to a wider gamut. [B]Fun Fact:[/B] If you're opening your camera's raw files using Lightroom, you're processing in ProPhoto RGB. Lightroom does not give you the option to modify the color gamut (at least not to my knowledge (someone please correct me if I'm wrong on this...)) but Adobe Camera Raw does. See the screenshot in hark's opening post. See all those options listed under the drop-down menu option, "Color Space"? Each of those is a different color-gamut she could process her raw files with if she so chose. I can only assume from that list she's also a fan of Canon printers. :) NTTAWWT. [/QUOTE]
