Why do Lightroom exports look darker on Flickr than on my computer?

When I export JPEGs from Lightroom 3 and upload them to Flickr, the files look slightly darker in Flickr’s viewer than they do locally. I’m exporting as sRGB. I noticed some apps show an EXIF color tag set to sRGB, while Lightroom exports don’t seem to show that, so I’m unsure whether this is a missing profile/tag issue, a browser color-management problem, or monitor calibration. The images look correct on my own computer outside Flickr, and another Lightroom user has seen the same behavior. What usually causes this, and how can I diagnose it?

Several things:

  • The exif "Color Element" tag is not directly related to ICC profile. Your image can have an Adobe RGB profile, yet still say "sRGB." Applications should use the attached profile, not the exif tag, when determining how to render colors. Ideally the EXIF color element tag should match the attached color profile, but there is nothing that will enforce the behavior.

This is definitely a color management issue. To diagnose try the following:

  • Download the image from flickr to your computer. open it in Photoshop PS and see if the image renders as you expect. If it does, then it's your browser's color management configuration. Firefox 3.6 does have color management, and while it's turned on by default, if you upgraded from Firefox 2.x, color management may be turned off.

To check:

  1. type about:config in the address bar
  2. hit enter
  3. click the "I'll be careful button"
  4. type "color_management" in the search bar

You should see three values:

  • gfx.color_management.display_profile
  • gfx.color_management.mode
  • gfx.color_management.rendering_indent

On my computer the values are (in order from above): blank (nothing),2,0

  • If the image doesn't render correctly on your computer, open the image in PS Elements and inspect the color profile, and ensure it's sRGB. If there is no profile, then LR3 either didn't actually embed a profile, or Flickr removed it.

  • Since the images right out of LR3 look right, double check that the embedded profile is sRGB. If it's not, then you likely have an export issue. If it's there, then Flickr removed your profile (which seems unlikely).

Generated from our catalog & community — verify before relying on it.

This is most likely a color-management or display-calibration issue, not a Lightroom export bug.

The EXIF “color space” tag is not the same as the embedded ICC profile. Applications should use the embedded profile to render color, so the absence or mismatch of that EXIF tag alone doesn’t explain the problem.

A good test is to download the image back from Flickr and open it in Lightroom or Photoshop. If it looks correct there, Flickr probably isn’t altering it in a meaningful way; the issue is more likely your browser’s color management.

Firefox 3.6 does support color management, but settings and monitor-profile compatibility can affect results. Some monitor ICC profiles—especially on wide-gamut displays—have caused incorrect rendering in browsers.

Also consider monitor calibration and brightness. LCDs are often set too bright, which makes you edit images brighter than they should be; then they appear darker elsewhere. Calibrating the monitor and using a reasonable brightness level can help a lot.

So: verify the downloaded Flickr file, check browser color-management behavior, and calibrate/adjust your monitor before assuming Flickr is the cause.
