The other new blending mode they added in After Effects CS5 is Divide and Divide…needs a little more explaining.…I have left myself in 32- bit floating-point mode.…And when I do that, the Info panel displays values from zero to one.…Black is zero so you can see as I am in this very dark area, my pixel values are…close to zero, white is one.…So as I move my cursor around these bright areas, the pixel values are near one.…That's important part of math to remember when working with Divide mode.…By the way, you make the Info panel display zero to one in any mode.…
You just need to change it to a decimal but I am leaving it on Auto…Color Display for now.…Okay, let's take a gray solid.…Its value is 50 percent or 0.5.…Well when you take a value and divide it by 0.5, it has the same effect as…multiplying it by two.…Dividing any number by a value less than one will give you a result that's…larger than the original number.…
So, in short, Divide mode tends to brighten the result.…I'll put my gray solid into Divide mode and you will see that my gears are a lot brighter.…
Chris and Trish Meyer have been using After Effects since version 1.0 and have written ten books about the program, and they are always among the first to dive into each new version and discover what it offers to their fellow motion graphics artists. Chris takes you under the hood and explains how each new feature works in After Effects CS5. This course covers both the technical and creative implications of this latest release, including tutorials on the new Roto Brush tool and mocha version 2, blending modes, text options, and new and improved user interface elements in Adobe After Effects CS5.
