I saw very washed-out colors when I uploaded jpegs to picasaweb.
Since then, I purchased a D700 and I've been shamed into using real
editing software. Now I'm using Capture NX 2 for editing.
Tinkering I've discovered or verified:
- Unless told otherwise, Nikon DSLRs create RAWs and jpegs with the "Nikon sRGB" color space.
- iPhoto generates jpegs with the "Generic RGB" color space.
- Picasaweb strips color profiles from images.
- When saving jpeg from Capture NX 2 _with_ an ICC color profile and viewing with PhotoMechanic:
- There is no perceptible difference between an sRGB jpeg and my "Nikon sRGB" reference image.
- My "Generic RGB" test image has faded highlights and _less_ vivid color than my "Nikon sRGB" reference image.
- My "Adobe RGB" test image has faded highlights and _more_ vivid color than my "Nikon sRGB" reference image.
- When saving JPEG from Capture NX 2 with or without an ICC color profile and viewing in picasaweb:
- There is no perceptible difference between a non-ICC sRGB jpeg and my "Nikon sRGB" reference image.
- My non-ICC "Generic RGB" test image has _much_ darker highlights than my "Nikon sRGB" reference image.
- My non-ICC "Adobe RGB" test image has _much_ less vivid color than my "Nikon sRGB" reference image.
- iPhoto is generating jpegs in a non-sRGB color space that looks substantially different when rendered as sRGB. Fail.
- Picasaweb strips color profiles from images, causing them to be rendered as sRGB even in colorspace-aware browsers like Safari. Fail. But at least behavior is consistent across all browsers.
- Don't use iPhoto if you want to put your images on the web. Outside of Safari, your images will look like crap.
- Only use Picasaweb with sRGB images. Images in any other color space will look like crap.
