Try reading some of our financial statements. I tried the same thing using LR 3.6 and PS 4 and PS 5.1 - same thing. If I open (edit in) PS and save the tif, viewing the two in LR (raw file and tif) the tif is much lighter, actually blown out. If I choose "develop" in LR for the tif, the brightness setting is much higher than the CR2 I chose to "edit in PS". As I suspected from the beginning, this is obviously a conspiracy to require an upgrade to CS6. Thanks much for your comments.
