I always have a problem deciding which exposure to choose when i am shooting some scene. I give you an example so it is easier to understand. Let say you want to take a picture of a landscape where everything is static, and focus at infinity. Your camera gives you the following setting: f/8 and shutter 1/125. Why would you choose this exposure instead of f/5.6, 1/250 or f/11, 1/60. The amount of light will be the same, everything is focus at infinity, so my guess is that the DOF will not change much. So what will be the difference between the 3 pics ? Thanks in adance for your responses.
