Understanding Histograms

1) It is the tonal range present in any giving photo. The graph is based on shades. On the right of the graph is black, and on the left of the graph is white. The higher the graph is, the more pixels of that color is on the photograph. So a dark picture would have high black, which on the left side, and a bright picture would have a high white, which is on the right.

2) When the histogram is at the right, it is dark. When it is on the left, it is bright.

3) A very good histogram should be focused on the center so it is high in the middle, and not as high on the sides.


4) It is a very good tool for photographers because it helps them fix mistakes. If the exposure is too high, then they can tone it down. If it is too low, then they can bring up the white lights.
