Understanding Historgam
Histogram is a feature in a DSLR camera that is often under-utilized by its users because of lack of understanding as what and how this histogram function works. Histogram, in general, can be viewed on the LCD screen by pressing the “info” button located next to the screen. Read on to learn more about what histogram informs the users about their photographs.
The X axis in the histogram illustrates the level of brightness/contrast ranging from totally black (level 0) to totally white (level 255), and therefore there are 254 levels of contrast in between. The & axis illustrates the pixel distribution in each level of said contrast.
Generally, a good photograph has a hill-shaped histogram with no cut-offs at the edges and at the peak of the hill shape. I say “in general” because there are some types of photographs (like a high-key, low-key, or night shot) where the histogram does not form this hill shape.
