Join Donovan Keith for an in-depth discussion in this video Animating rack focus, part of Production Rendering Techniques in Cinema 4D.
Blur is one of the primary tools of the cinematographer, and shifting the focus of a scene could be…used to excellent storytelling effect, whereas haphazard focus can be distracting or even stupefying.…Let's take a look at some variations on animated focus.…In the first, I'm going to be adjusting the focal distance of the camera.…We see that the background starts in focus, then the foreground, then the background.…This is probably the most common animation of focus that you're going to see or adjustment…of focus you'll see in film, which is the pulling of the focus ring.…
In fact, that's a job on a film set, the focus puller there is a person dedicated to just adjusting that ring.…Next, we have an aperture adjustment, where we're animating the F-Stop.…This is less common, but an interesting effect.…The focal point is staying the same but the amount of blur in the scene is increasing…or decreasing as we adjust the F-Stop.…Lastly, I'm going to use a constant focal distance and just animate the position of the camera.…
