For jpg often the good old sRGB profile (most common standard) is better because most webbrowsers don't understand the color managment.
Support for .tiff images (core or plugin) with advanced ICC profile such as AdobeRGB1998 (more colors for other media) or ProPhoto (even more, it really makes visible sense even on the computer) as they are got from CaptureOne really would be useful, also because irfanview can read them correctly now and show the image appropriately on the PC. I understand it's not possible till tomorrow but please keep it in mind. :wink: old thread, but still better than a new one.
Today paint.net can read those .tiff files out of CaptureOne with large ICC profile color spaces, but the colors are shown wrongly, with much too less saturation. The advanced ICC profiles are becoming popular among amateurs as me and it's one of the few things which Photoshop still can do better.
