Blend Mode Description


Recommended Posts

When I use layer blend modes, I can chose from a list of modes ... that is nothing new.

Is there a description available, of what those modes actually do??? And I do not mean this mode lightens up etc. I want a more mathematical view like:

For the sake of explaining lets assume we are talking about RGB colors, so rgba values. The function F_Mx is the function for blend mode Mx, it takes the pixels color values

C_b(P)=(r_b, g_b, b_b, a_b) which is the color value of the pixel below the current layer and

C_c(P)=(r_c, g_c, b_c, a_c) which is the color value of the pixel in the current layer, i.e.

F_Mx(C_b(P),C_c(P)) = <insert formula here>

This would help me very very very much, to wrap my mind around it, the blend mode names are in itself not explanatory enough (and yes, I am in the Asperger spectrum).

Cheers, Frank
