On the Digital Photography School website I found a 100-things-about-photography list that is very useful. So I report here not all the 100 things, but only the more important ones.

  1. Enjoy what you are shooting.
  2. Pay attention to your thoughts and emotions while you are shooting.
  3. Set goals you can achieve.
  4. Write tips about photography, beacuse writing is also learning.
  5. Never go shooting without a tripod.
  6. Watch the place you want to shoot first wirth your heart then with the camera.
  7. Perspective is the killer.
  8. Keep your camera clean.
  9. Find your own style of photography.
  10. Try to compose more and to hit the shutter less.
  11. Take care of the golden ratio.
  12. 10mm rocks!
  13. To give a landscape photograph the extra boost, integrate a person.
  14. Always shoot in RAW.
  15. Discover the things you think are beautiful.
  16. The best equipment is that what you have now.
  17. You can't take photographs of everything.
  18. Pay attention on the different ways that light falls on different parts of your scene.
  19. The eye moves to the point of more contrast.

  24. It's who's behind the camera, not the camera.
  25. Shoot as often as possible.
  26. Re-check your ISO settings. It's aweful to detect the wrong settings on your screen.
  27. Try to amplify your mental and physical limits. Take some extra shots when you think "it's enough".
  28. Pay attention to structures in the sky and wait until they fit into structures in the foreground.
  29. Ask yourself: what do you want to express in your images?
  30. Photography is never a waste of time.
  31. A better camera doesn't guarantee better images.
  32. Post processing = optimizing your image to te best result.
  33. If you have an idea an immediately you think "no, this is not going to work", do it anyway. When in doubt, always shoot.
  34. There will always be people who will not like what you are doing.
  35. Henri Cartier-Bresson was right when he said: "YOUR FIRST 10,000 PHOTOGRAPHS ARE YOUR WORST."
