Low and High percent what is this actually doing?

Hi :slight_smile: I just need a bit of clarity and in much more simple terms, what these settings are doing?

The description on the documentation I find a little hard to follow

Low Percent Auto exposure adapts to a value extracted from the luminance histogram of the scene color. The value is defined as having X percent below this brightness. Higher values give bright spots on the screen more priority, but can lead to less stable results. Lower values give the medium and dark values more priority, but might cause burnout of bright spots. Values should be greater than 0 and less than 100. A good starting range is 70 to 80.
High Percent Auto exposure adapts to a value extracted from the luminance histogram of the scene color. The value is defined as having X percent below this brightness. Higher values give bright spots on the screen more priority, but can lead to less stable results. Lower values give the medium and dark values more priority, but might cause burnout of bright spots. Values should be greater than 0 and less than 100. A good starting range is 80 to 95.

Do you use the Low / High percentage settings to remove unwanted pixels from the Histogram you don’t want the auto exposure adapating to? e.g dark blacks from shadows and super bright white highlights from fire etc.

Shows you these pixels

Thanks!
