Join Mark Christiansen for an in-depth discussion in this video Create depth of field with a depth map, part of After Effects Compositing 02: Matching Foreground to Background.
…Suppose you want to create shallow depth of field…effects within a single layer, instead of between multiple layers.…For this you need to assign a blur map.…Blur maps, also known as depth maps, can be created…by hand and in this lesson I'll show you how.…The basic idea is to generate a grey scale gradient that…corresponds the distance from camera of specific areas of the scene.…So here we have a ground plane that extends…from the camera to a wall in the background.…Now let's suppose I want just one or the other of these skateboards to be in focus.…
That's going to be fairly simple because it's just a straight line back in…space, along a flat plane with two objects very close to that plane.…So I can achieve this with a simple gradient.…As you know, I can create that just using a solid.…I'll call it, grad.…And it doesn't matter what color it is, because I'm…immediately going to assign Effect > Generate > Gradient Ramp.…So now I have a gradient that describes…the foreground and background as white and black.…
