Live histogram

The histogram is a powerful guide to evaluate a photo exposure.

A histogram is a graph that counts how many occurrences of a particular
brightness channel has. In case of color photos, there are three color
channels (red, green and blue) each with its own intensities, whereas in black
and white images there’s only one luminance channel. Also, even with color
images, you can opt to get a luminance-only histogram. Internally, the picture
is converted to grayscale to calculate the histogram.

Activating the live histogram

Go to

Settings > Viewfinder > Live histogram

and activate Show histogram.

The histogram is calculated in real time and changes when you move the
camera or the subject, or you change settings that affect the lightning or color
distribution.

Histogram types

In

Settings > Viewfinder > Live histogram > Histogram type

you can select:

Highlights

Shadows
