When you shoot the objects, it is often necessary to correct the background. The Background correction option levels the background colour, eliminates irregularities and dark parts.
The Background Correction dialogue window is available from the File main menu.
Let's take a look at the settings of the dialogue window:
Process Background switches on/off the background processing.
Background Equalization with Color Correction and Automated Background White Balance are 2 different modes of levelling the background. To define what mode will bring the best results to your image, apply each of them one by one.
For the Automated Background White Balance mode, you can use the Gain setting which allows choosing the degree of background brightening.
The Process background on preview setting shows changes of the background in the preview window.
