I have just purchased & installed PSE12 and want to use it as a external editor with Lightroom 4. I have set up LR4, but when I ask LR4 to edit a photo in PSE12, the PSE12 Editor opens but no image appears. I had an older copy of PSE8 set up this way, and the editible image appeared just fine. What do I need to do differently? In LR4, I have PSE12 set-up as an additional external editor with PSD format, 8 bits, Adobe RGB (1998) and 300 resolution. I am working on an iMac running OSX 10.8.5.
Thanks in advance for any help with this
