Suddenly this question hit into my head. If we know what are the common problems, we really can avoid them
1. Leaving the ISO set to 1600 when you are shooting in bright daylight
2. Arriving at your location and found out you didn’t bring memory card or film
3. Not using tripod for slow shutter speeds and then discovering all your photos are blurred
4. Putting a filter in your jacket pocket, taking the jacket off and then sitting on it
5. Picking up your camera bag when it’s not zipped up and the contents drop out
6. Forget to charge your batteries and only found out after you have leaved home
7. Failing in the river, lake, sea when you are carrying your camera bag which all your gears are in
8. Turning up to photograph an event the day AFTER the event (is it possible? hehe)
