An overlay with the same picture looks like an S-curve. formula_5 where "a" is the base layer value and "b" is the top layer value.

Hard Light is also a combination of Multiply and Screen. Hard Light affects the blend layer's relationship to the base layer in the same way Overlay affects the base layer's relationship to the blend layer. The inverse relationship between Overlay
