Well, posting examples would help. But check your color space first, needs to be sRGB.

I have LR 4.1 and no such problems. Exported JPGs look fine. Did you check the Adobe forum? http://www.lightroomforums.net/showthread.php?17807-Exported-JPEG-photos-appear-darker

Hi Guys,

Thanks for your responses.

Okay here's a sample that I submitted to iStock.





This is what they sent back to me showing me why they rejected the image due to lighting issues. This image was mocked up at their end by the way.

To the LEFT, is the one I submitted. To the RIGHT, is the one THEY corrected.

Funny thing is, in LR 4.2, my original looked like the one on the RIGHT. I double checked it today and I don't see how they managed to get an original from me which is SO DARK? That gamma's wayyyy off.

I checked my JPG export presets and they're all set to sRGB by default anyway, so they should be right. Any ideas?

Thanks in advance.

Hey Mark! Mate, It's you again

I have an iMac 27" at the moment - it's been calibrated by the System Prefs tool. What do you use to calibrate your monitor?

Looks like I screwed up during the isolation cleanup in Photoshop. Thanks Rimglow!

this might be a  stupid question, but do you have to process the image in order to export it? (I only know ACR which is basically the same at LR).

You don't have to do anything in LR - but it's doing a RAW conversion (based on settings and preferences) to a JPEG of the size, compression and in the color space you specify, so LR is doing some processing even if the user doesn't.

This sounds like a profile mismatch issue or an uncalibrated monitor - did the OP ever get things figured out?

perhaps I didn't explain it clearly:
LR, like ACR, is non-destructive editing. So whilst changes you make show up on screen they aren't applied until you press the go button (in ACR it's called Image Processor). I appreciate that you can't upload RAW files, but if the OP was starting with jpegs there's a chance he didn't process the changes and sent them thru SOOC.

When you export from LR, if you shot JPEGs, any adjustments of any kind you made in LR to the JPEGs would be included in the exported file - you can't export the unchanged image by mistake. There's no "go" button for applying any adjustments as they're auto applied, if that makes sense.
