If the Amplitude slider is 0: No brightening is applied.
If the Amplitude is 100 - 200: Proportional amount of clipping increases.
In most cases, 110 is the right amount of amplitude. For images with fine
detail in the highlights, decreasing brighten amplitude preserves the
detail.
In most cases it is not necessary to adjust amplitude.
