No RAW file being displayed, those are all JPEGS (TIFF displays the same in Lr 4 - incorrectly). That image is a screen shot of the SAME file being displayed in 3 different programs.
Re-importing didn't change anything.
Monitor is a Dell 3011, it hasn't been calibrated in a while, but that shouldn't matter - it isn't ALL images that are displaying incorrectly, just Lr 4. (I'll be calibrating again soon - i1 - but I can't now due to technical issues with two computers)
PC, Windows 7.
Thanks
