I recently found that when I uploaded images to Flickr, they were desaturated a little bit. Also, when I tried to open my photos with Windows Photo Viewer, they were the same sort of desaturation when I put it in full screen, but NOT when I just opened the image, just when it was in slideshow view.
This only applied to photos I'd edited in Lightroom 3 and not any other so I changed a few settings in lightroom to experiment how to get my photo exporting (from Lightroom) back to normal again. Yesterday I edited a friend's photo and downloaded it from an email, (he uses a canon g12). Because yesterday I edited a friend's photo using Lightroom, that may have changed some settings automatically.
I noticed that the color setting when you export photos was ProPhoto RGB, instead of sRGB. I changed to sRGB and now I think everything's fine with the pictures and it's back to normal, BUT:
Should my photos be exported with sRGB or ProPhoto RGB? Because I do not know what it was before this kerfuffle happened.
Any other idea's on what I should do? Not completely %100 sure that it's back to normal yet :/
