Photographer's nail gun: Histogram

Photographer's nail gun: Histogram

A histogram is nothing more than a bar graph. It shows how the luminance values in a digital or digitized photograph are distributed. The linear scale in a histogram runs from black at one end to white at the opposite end.

It's about Histogram in DSLR cameras. It looks like a small criss crossed bar graph, but it holds true information on color scattering details of the photograph. I mostly shoot pictures in RAW format (ARW in sony alpha 100). Though I'm able to read Histogram partially, it needs to have a perfect & expert knowledge on how histogram holds information about luminance values in a digital photograph.

I found a detailed read on histogram & what histogram has to offer in digital pictures.
