- White Level sets the white point of an image. higher number makes white brighter, lower makes darker.

In the case of the Pleasantville Effect, we all know it's to convert parts of a colour photograph to a black and white one, but it can work in reverse also, using the same cutting out of parts applying an adjustment to it - that is exactly what you need to do to colourise a black and white photograph.
