Rendering bokeh with Depth of Field

- [Instructor] Our final special effect is a depth of field,…or bokeh effect, in which distance determines…the amount of blurring in a rendering.…This simulates the way a real camera works.…The amount of blur is based upon distance…and the size the aperture or iris.…Increasing the iris size, lowering the F number,…will result in a shallower depth of field.…And you can use this as a method…to direct audience attention…and we can also animate the focus distance…to create a rack focus effect.…

I've got a Physical Camera in the scene,…select that camera.…The easiest way may be to select the viewport label…and then choose Select Camera.…Go over to the Modify panel,…and scroll down a little bit…in the Physical Camera parameters.…Under Focus at the bottom of that you see a switch…to Enable Depth of Field, turn that on.…And now we see in the Perspective view and the ortho views…there are additional planes attached to the camera frustum.…

The center plane, which is a little bit more blue,…represents the focus distance,…which is driven by the Target Distance.…
