Blend modes inverted again. This yields the opposite effect to multiply. The result is a brighter picture. formula_4, where "a" is the base layer value and "b" is the top layer value. This mode is "symmetric": exchanging two layers does not change the result. If one layer contains a homogeneous gray, Screen blend mode is equivalent to using this gray value as opacity when doing “normal mode” blend with white top layer. Overlay combines Multiply and Screen blend modes. The parts of the top layer where the base layer is light become lighter, the parts where the base layer is dark become
