Merging multiple photographs into a single large panoramic photo can yield excellent results and with the proper software it can turn your small sensor camera into a 30 megapixel digital camera. Adobe Photoshop CS4 has an excellent Photomerge feature that automates the tedious process of lining up and merging multiple photos into a single larger photograph. Below is the procedure for merging multiple photos into a single panoramic photograph in Adobe Photoshop CS4. 1) Open Photoshop and select "File" and then "Automate" followed finally by "Photomerge. 2) Next you will be greeted by a dialog box with several options. The Layout options give you many choices in how the final outputted file will appear. For good results I usually leave it on "Auto" and let Photoshop decide, this usually gives me decent results, but feel free to experiment with all the options here. 3) After you have selected your layout you need to select the source files.
