If you are not confident with dialing in the correct exposure for an important shot BEFORE you take the shot what should you do? There are a couple of tricks to remember: Firstly, set your camera for exposure bracketing (-2/3 - 0 +2/3) focus and keep your finger on the shutter for 3 shots - you'll probably find you nail it - although results can be less predictable if using ETTL flash.
Secondly, flip your camera into Liveview (assuming you have the function on your SLR) and you can now see the actual exposure in realtime - play around with your dials and WYSIWYG (unless you are using flash). Liveview can also be great for checking the DOF for a shot - keep your finger on the DOF button and dial your apperture in realtime on the screen. Failing all that, ensure you have Adobe Photoshop or Lightroom 2 , and you'll be amazed what you can fix if shooting in RAW (within reason of course).
