Hi there! Because the forum you originally posted in is for beginners trying to learn the basics of Photoshop, I moved your question to the Photoshop General Discussion forum, where you'll get more specialized help.
Photoshop cs6 doesn't have the automatic fill when doing panos as pse 11 does, but really that's a good thing, since you have much more control in photoshop of
Try something like this:
1. After the photomerge completes press Shift+Ctrl+Alt+E (Shift+Cmd+Option+E mac) to merge the pano into a new layer at the top of the layer stack.
2. Ctrl (Cmd) click on that layers thumbnail in the layers panel to load a selection of the transparency
3. Press Ctrl+I (Cmd+I) to inverse the selection (Select>Inverse)
4. Go to Selecte>Modify>Expand and enter a value between 5 and 10 px
(You may need to expand more or less depending on the size of the pano)
5. Go to Edit>Fill and choose Content Aware
6. Then go to Select>Deselect or press Ctrl+D (Cmd+D)
That's basically what the edge fill in pse 11 does for panoramas.
Thanks a lot, will give it a try!
Well, works till Step 5:
When clicking the OK Button I get the following german Text:
"Konnte die Fläche nicht füllen, weil es nicht ausreichend deckende Quellpixel gibt".
Translated to English nearly:
"Could not fill in, since there are not enough source pixels".
It would be helpful if you would capture your entire screen at the moment of that error, save as a JPEG, and post it here. Often people can spot what's gone wrong.
I can say that the instructions, as written, do work. I do that quite often.
