| I still haven't figured out when to use a low ISO (50) and when to switch to a higher one (400)?? Can anyone explain the differences to me?? |

You should only use an ISO over 100 if it is a low light situation, especially when you need a fast shutter speed. A higher ISO will let more light in, but causes noise (more so with digital). Use the lowest ISO whenever possible for better quality. If there is not a lot of light but you don't need a fast shutter speed, then use a tripod and keep your ISO at 50.

When you have to hand hold the camera without flash and you are shooting some kind of action shot indoors a higher ISO of 200 or 400 is usually necessary. If you have a tripod and are shooting slow images or scenics at night it is best to keep the ISO as low as you can to avoid too much noise. A lot of people mistakenly think that you should use a high ISO in this situation but since the camera is mounted on the tripod and you are using slow shutter speeds you will probably have enough light to work with. This is also a common misconception when photographing a sporting event out doors in bright sun. A low ISO and fast shutter speed produces great results because you already have plenty of light. Action doesn't have to mean high ISO but low light might.
