Large Panorama
Usually when you create a panorama you have to crop the image after it has merged everything together onto a transparent background. Doing so you usually end up cropping off some of the picture that you want to keep. But, not with CS5. Instead you can select that transparent background, modify selection to expand it into the picture about 25 or so pixels, then use Content Aware Fill.
This is a pano of 17 vertical/portrait pictures taken on the boardwalk of RiverView Park, Swansboro NC.
