Without \"-color\" if defaults to \"-color sRGB\" and you get\ndata that has been, after white balance correction and denoising,\nconverted to sRGB, with gamma. As Roland just pointed out, there is no\nstandard for representing linear RGB, and this is why we haven’t added\nthe option to generate it.\n\nOn lun, 2016-08-01 at 06:21 -0700, adrienlucca wrote:\n> Hi,\n> \n> thanks for the comments.\n> \n> So what happens if I simply use the -tiff -color none switches ?\n> I can see that it seems linear, however:\n> \n>       * What is the content of the RGB channels?
