My photos look great on my Adobe RGB calibrated monitor look great and print "spot on" to my printer.
But, when I export the photos via Lightrom's PDF/RGB export utility, the colors end up looking terribly dull on my website. I am following the LR defaults to convert the photos to RGB. So what is the problem ad how do I solve it?
Got Help?
I do not get the "calibrating monitors to AdobeRGB....."
My monitor is calibrated to say 5000K, 110 cd/m2, 2.2 Gamma and then profiled to describe its gamut with the profile to the color management system. That wide gamut monitor more or less exceeds AdobeRGB in gamut but another one that I have stays way below, probably just sRGB, yet has the same 2.2 Gamma.
AdobeRGB and sRGB have 2.2 gamma, ProPhoto 1.8.
I guess your problem is related to the fact that ProPhotoRGB has 1.8 Gamma and your workflow 2.2 Gamma, though one would expect adaption in the software. It could have to do with image files not having the color space assigned at export or similar CM flaws. Check the import color management policies in your software. Set preserve embedded spaces and let a warning pop up on any mismatch or profile absence. Load the image intended for the web again and check what the assigned color space is in the warnings.
It is possible that LR does it wrong in your case.
Export to the web is done in RGB with sRGB color space profile assigned to the image. That is the best compromise today on usable color spaces with CM or no CM available on the world's web displays. Depending on your browser it has CM aboard (but the default can be "CM off") or not. So your browser may not cope too. Check its settings. Use more browsers to check web designs if they are intended for a wider audience. Firefox, Explorer, Chrome, and the smaller ones after that.
