Have you ever been so close to a subject that you just couldn’t get it all into the frame? You could use a fisheye lens but they creates so much distortion that it doesn’t always work the way you want it to. You can actually get the photo that you want with the lens that you already have! You can accomplish this by taking multiple images over several columns and several rows, and combining them into one very large, extremely detailed image.
PhotoMerge acts as the lens you would need to capture large subjects within your frame. By taking multiple images you could create this very image of a space shuttle, like above.
