Understanding Exposure by Iberionex Perello

Understanding exposure is something that I need to work on more.  I often find myself taking far to many shots trying to find the right exposure rather than having a better understanding of it to begin with.  Iberionex is one of the instructors from BetterPhoto.com who has a podcast series on light in photography.
I just love how he "sees" the light in his photos and how he explains it.
