The new Live View feature on digital cameras is in my opinion the biggest thing to effect camera design in decades!
This feature lets you see your image the way it will come out in advance of your shooting it. What you see is what you get! This is huge, not only will you see your exposure which in effect warns you of an improper camera selection/solution plus exact framing but in many cases with even show you your depth of field (area of focus). When used in conjunction with integrated Exposure Compensation you can correct your exposure on the fly thus greatly reducing even eliminating the need for post production time.
No longer do you have to have a complex understanding of over and under exposure adjustment to just adjust till it looks good! The Pros often call this a gimmick. cheating and a useless feature; I call it the path to better color, sharpness and composition.
