Hi All,

This is driving me insane... perhaps one of you guys might have the answer.....

I’ve been getting more and more frustrated with my shots after I export them to JPG. In Lightroom I get them looking “just so”, however after exporting to JPG I seem to lose way too much detail, and they become too dark and contrasty.

I took a screen shot of before and after which best describes the problem:

(ignore the random photo :) )

I thought it might be a colour space issue, but I’m shooting the same as i export in. Export settings:

Perhaps my monitors need calibrating or something? Be interested to hear a Pro’s thoughts!

Thanks,

Matt
 
I'm not a pro, but...

Lightroom uses the ProphotoRGB colour space, which has got a wider gammut than sRGB.

Also is Windows picture viewer colour space aware?

Hiya,

Thanks for your response.

Correct me if i'm wrong, but it shouldn't matter what you view the JPG in - it will look the same everywhere?

You see to me, there is a significant difference between what I'm seeing in Lightroom, and what I see once its converted in to a JPG.

The interesting thing is that if i export a TIFF, it looks spot on....?
 
You could try exporting in the ProPhotoRGB colour space to see if it is the sRGB making the difference, although that would only work if you're opening the file in a colour profile aware application, such as Apple Safari.

Maybe someone will be able to clarify if Window picture viewer is colour profile aware.
 
Windows veiwer is not colour managed, also one should bear in mind that in a none colour managed application you are veiwing the image in your monitors colour space which is not srgb and is native to your monitor profile ( unless you have specificly set your monitor to a srgb profile).
 
Hmm I just tried this on Vista.

I took an exported image and viewed in the windows viewer and Picasa.

Definitely some differences between the windows viewer and Picasa. So maybe you want to try that?

Note that the difference between images isn't as extreme as your picture above, but my monitor is calibrated so windows applies the calibration profile.
 
The example you've posted looks like the main change is in luminosity rather than colour, so I'm wondering if it happening because you're exporting a 12/14/16 bit image to an 8 bit JPEG. The slight banding evident on the background wall and the mans head makes me think this might be the problem.

If you view a proPhoto (wide gamut) image in a non colour managed viewer that assumes everything is sRGB you should loose saturation, not gain it.
