Thus the fancy name. Same happens for our AdobeRGB profile. However, they are supposed to be identical to the "original" profiles (*), just the name differs. That being said I have no idea what Blogger does to your images. Could you maybe export a tiny image (300x200 pixel would be enough) using darktable's sRGB profile, upload it to Blogger and also attach it to a mail here and give us the URL? Maybe we can make some sense from it. > Thanks, > > Rich Tobias (*) this is true for AdobeRGB. For sRGB however there are a couple contradicting definitions of how the profile should look like. We use the most common/accepted version.
