I recently updated from LR3 to LR4. My edit in Photoshop preferences are for a psd.
When I "edit in Photoshop" using LR4, Lightroom immediately creates a "filename-edit.psd" file. With LR3, only when I saved from within PS did it create the new file edit.psd file. I like to keep the option open to use "save as" and save just a jpg if I know this is going to be my final edit and not have a psd. Now if I save as a jpg, I end up with an extra .psd file. Is this a change in LR4 or have I not set something that I had set in LR3?
I think I now see what's happening. In LR3 I could get away with the "open anyway" option, but in LR4 I have to use the "render with Lightroom" option (since CS4 doesn't support latest ACR). That option produces the immediate .psd while the open anyway option that I was previously using doesn't.
