Difference, Exclusion, Subtract, and Divide

In this movie, I'll demonstrate the fifth group of blend…modes which are color coded in purple inside of this diagram.…The first two, Difference and Exclusion, are Inversion modes that…have been included in the software for a long time now.…The other two are added recently, and they're known as the Cancellation modes.…And the thinking was, according to some programmers at…Adobe, they wanted to round out the basic arithmetic.…So, where the Layers panel is concerned, we already…had Linear Dodge, which adds luminance levels.…So, we might as well get Subtract as well.…

And then we've got Multiply, which actually does multiply Luminance…levels, so they figured they might as well add Divide.…Neither of them is terribly useful for layering.…And in truth, they're duplicates of Lend modes that already exist.…So, let me show you what's up here.…I'm going to switch over to this version of the image with the light bulb.…And…I'm going to scroll down to the wrestlers layer go ahead and select it.…And I'm going to change the blend mode from linear burn to difference.…
