1. Try to get the best exposure from the beginning, don't rely on post-processing
2. Concentrate more on a cleaner background than on the subject
3. Always use the rule of thirds
4. Use a large aperture when you want to blur the background
5. Telephoto lenses provide much better bokeh
6. Scattered clouds make for the best skies in landscape photos
7. Take multiple photos in burst mode to minimize handshake
8. The faster the shutter, the less of a chance for a blurry photo. This is, of course, is at the expense of enough light entering the lens
9. In Photoshop, the menu items "Crop", "Levels" and "Brightness/Contrast" should be the first things to be used in any photo edit, and in that order
10. Take your photos as RAW (if your device supports it) and then convert it to JPG in post-processing. RAW captures light much better than JPG and hence provides you with much more flexibility in editing.
