What does the level clipping filter do?
Level clipping is a technique that maps nearly white pixels to be absolute white and nearly black pixels to be absolute black.
Level Clipping Filter — Before
Level Clipping Filter — After
By default, white pixels have a value of 255 and black pixels have a value of 0. The white and black input level sliders map the white point and black point.
This filter is typically used to force the nearly white background of an image to be absolute white.
As of uScope Navigator v4.3, the white level can be configured to clip to the selected pixel value rather than absolute white. This yields more pleasing images.
