Here is a great post I came across at Memories Valued that shows how to make the most of your photos using the photos histogram.
The histogram is a useful but often misunderstood tool your camera provides to help you get the correct exposure on your images. In this article I’m going we’re going to look at how to read it, and use it to your advantage to help you do just that. Getting the best exposure (there is not such thing as the “correct” exposure, as it’s all subjective, we’ll talk about this more later) in camera should be your goal every time you click the shutter. Using these tips should help you increase your success rate.
