This doesn't work to make me be able to superimpose them to make the original for many reasons.
Firstly truning the contrast to 100 leaves just black and white and thus you can imagine what putting iut even on 75% would do (the black and white take over), and the luminoscity i need that layer to be see through in places where the hue need to shine through to make the effect of the original...
So no this is a faulty attempt, at this effect i think would give user good control over images.
