This is going to be a fairly long tutorial on stitching two images together using Photoshop Elements 5 or using the full version of Photoshop. There are lots of stitching programs out there, but this method offers alot of flexibility. I first started doing this to extend the Field of View (FoV) of the kit lens that came with the D70, but there are other advantages to doing this as well: increased sharpness, better dynamic range, and a larger image than you would normally be able to create.
Start by taking two images, one of mostly the sky, and another of mostly the foregound, remember to have some overlap , and include the horizon on both images.
I posted this as a tutorial in the technique group:
