I have issues too. First LR4 didn’t bring over LR3, I had to go back and open new catalog and then bring in LR3. Not sure about tone curve issue yet but noticed in the Develop area the LR3 version is now there. When LR4 opens the shadows and highlights you can see then grayed while uploading program. Once fully uploaded then it changes to LR3 wording of fill light and Black.
Do you know anything about this issue or maybe I did something wrong?
Jan – Lightroom 4 introduces a new process version labeled “2012” which replaces the process version from Lightroom 3 labeled “2010”. You will find it under the Camera Calibration panel in the Develop module.
Pictures you’ve already edited in LR3 should be left alone, which is why you see the Develop module sliders from LR3. IF you change the process version of a previously edited image to “2012” you will see the updated LR4 sliders.
Any new images imported will automatically be assigned process version 2012.
Thanks for the hint! But doesnt LR make a new copy anywayin the update process? As I open a LR3-catalog in LR4 and click “update” in the dialog window, a copy “…-2.cat” is being created. Is that a different matter?
Wilfried – it does, but this was a good opportunity for me to remind folks not to take anything for granted, and I always make my own copy first because you never know when/where something might fail.
