No..haven't gotten the 8.1 upgrade...will D/L it though :)
Sorry Rob...lighten and darken are not the same thing as add and subtract. Yes they do a simular effect, but they arn't even remotely compatable.
Add = just what it says, add the pxel color values of one layer to the pixel color values of the layer/background you are mergeing it with...follow along
background = 127, 127, 127 (Red, Green, Blue)
merge layer = 127, 127, 127 (Red, Green, Blue)
add them together = 254, 254, 254
lighten and darken work off the diiference in pixel color values. which is why the resulting pixel colors don't change if they are the same values from merge layer to background layer....but with add and subtract they do.
