Enough theory, you are now ready to try some focal effects of your own.
You can use the Lens Effects Focus module in Video Post to replicate a film camera move used to draw the viewer's attention from one specific character or object to another.
The method you use here shifts the focus from a distant object to a foreground object, forcing the viewer to see something that might normally be lost in a busy scene.
Focus changes are an important part of cinematic storytelling and should be considered in computer animation as well.
Pay close attention to focus the next time you go to the cinema or rent a video.
n Focus adds focal effects through blur.
The Focal Loss parameter enables you to add more or less blur to the scene.
By unlocking Horiz.
and Vert.
Focal Loss, you can blur the rendered image more or less along a specific axis.
*Use general blur settings for non focal point effects.
You can use both Scene Blur and Radial Blur to blur a scene without depending on the Z-Buffer.
Scene Blur blurs the entire rendered image, and Radial Blur blurs the scene from the center of the rendered image outward.
*Focus is based on Z-depth.
Because of this "feature," focus begins and ends focal effects based on a planar range rather than spherical.
At higher Focal Loss settings, this becomes very noticeable.
*Use dummy objects when simulating focal shifts.
Rather than using the target of the camera, create a dummy object for your Focal Node.
This enables you to create focal shifts without moving the camera or its target.
