Same old drag and drop photoshop technique. I cut out each component from the original photo, drag it into a transparent frame, clean it up the rest of the way, then drag it into the composite image, which starts out as the picture of Mt. Hood. When you drag something into another picture, Photoshop automatically puts it on its own layer, so you can adjust brightness, contrast, color balance, size, etc. When you've got it just right, you "flatten" the image and save it as TIF or JPEG (or whatever).
