Here's a pano of Silver Creek I took and generated yesterday. I use Adobe Photoshop CS5's photomerge tool. Stitching together 76 RAW images took a minimum of 2 hours on my computer. I just left it working and did other things. After stitching the images together the single file is now 173 mb and 59.8 megapixels. I used my 50 mm prime lens, shot at f8 and used auto exposure lock and auto focus lock(AE-L & AF-L).
