(I'll have to figure out what colorspace fu is making my uploaded photos be desaturated when I view them.)

If you are processing in AdobeRGB/ProPhotoRGb/most decent color spaces (for optimal printing purposes) and then dont a)include the ICC profile and/or b)convert to sRBG profile before uploading, the smaller gamut profile's interpretation of the larger gamut image will be desaturated.

Thanks.

I'm in LR, and in the export I've got "sRGB" selected. It seems like it's scaling the broader gamut down to sRGB, and I need to find a way to tell it "yo, try clipping it and see how that looks."

Interesting. If I export to a JPEG on disk, it says it's sRGB, and that JPEG looks about right in the Preview app, but desaturated in Safari or Firefox (either opened locally, or uploaded).

Grmf.

Thanks, that looks like a pretty good summary.

The key piece I had been missing (which that page mentions clearly) is that when people say "Firefox assumes unprofiled images are in sRGB", they're confused. Firefox just shovels raw bits at the video card.
