Next I want to talk to you about setting Hue / Saturation settings. First I want you to understand the definitions of each of these terms.
Hue: Hue is the aspect of color which is described as “red” or “yellow” etc. It is one of the three main attributes of perceived color. The other two are saturation and brightness.
Saturation: purity or strength of color, due to the absence of black, white or gray.
Brightness: Color brightness has to do with the amount of light added to a color.
Before you start using the hue / saturation tool I want to caution you with going overboard with it. Amateur photographers will often discover these tools and then overuse them so much that their photographs become unrealistic looking. This is fine if you are going for a surreal look, but if you’re looking for photographic enhancements then use this tool with extreme caution.
The purpose of the tool is to alter the vibrancy of the colors in the photograph. You can choose to either enhance dull colors or artificially dull bright colors. Both choices can have some interesting visual effects. Take a look at the following photograph for example.
