- A blog post based on conversations with participants during my photography classes.
A histogram is a graph that gives us information about the tonality of our photograph. We should be able to display it when reviewing our pictures on our camera and in photo editing software.
The horizontal orientation of the histogram gives us information about brightness. The left part of the histogram starts at the left black with no detail, (0% brightness) the right part of the histogram ends at white with no detail (100% brightness).
The vertical orientation gives us information about how many pixels are a specific brightness.
There’s also a histogram that shows color distribution, usually in terms of RGB (Red.Green.Blue)
Personally, I don’t use the histogram to evaluate my picture.
I use my picture to evaluate my picture.
After all, what are we going to hang on our wall, our histogram or our picture?
