Automatically recognize photograph histogram and set level for shadows and highlights.
This function automatically recognizes the photograph's histogram and sets the level for shadowing and highlighting. It is a convenient function for when lighting conditions are weak (low contrast) and you want to set tones used to the maximum of RGB gradation. Sometimes a strong level correction raises the contrast, leading to a higher chroma. If this happens, use the chroma slider to lower the chroma.
It is possible to finish using a maximum of gradation even in scenes with weak lighting conditions. You might want to make adjustments to input / output levels after basic automatic level corrections.
You can create lively, bright photographs by performing automatic level corrections even in photographs that appear sleepy under conditions of gentle light with little differences in brightness.
