What is going on?

This is an endless pain. I am editing a raw .dng file in Lightroom, then go over to photoshop for corrections and then save it back to lightroom. It saves as a tiff - that I know. But the colors look totally different, also the curve looks totally different. It seems as the tiff file has lost a huge amount of vibrance and image fidelity. Why is this happening?

Hi there,

Sorry to hear about the color difference, could you try changing the screen color profile to sRGB IEC61966-2.1:?https://www.lightroomqueen.com/how-do-i-change-my-monitor-profile-to-check-whether-its-corrupted/

Relaunch Photoshop and Lightroom after changing the screen color profile and let us know how it goes.

What is different from what, exactly? Raw from TIFF? Lightroom from Photoshop? Library module from Develop module? Be specific.

Make a new comparison, and make sure both display at 100% or 1:1. This is important - if there is noise or a lot of fine detail, different screen resampling algorithms may affect the apparent result.
