A photo's color intensity can be modified by changing the brightness and content.
fiasKO [112]
The above statement is FALSE.

A photo's color intensity can be modified by changing the brightness and CONTRAST.

There are four common image controls that makes an image easy to view. These controls are brightness, contrast, saturation, and sharpness.

Brightness control simply brightens the whole image from the shadows to the highlights equally.

Contrast control is the separation between the darkest and brightest areas  of the image.

Saturation control is the separation of colors in the image.

Sharpness control is defined as the edge contrast, meaning the edges in the image are the ones being contrasted.
