The Weile Woods

A split focus diopter is an unique way to achieve the illusion of deep focus. The half convex glass attaches in front of the camera’s lens to make half the lens nearsighted. The split diopter allowed directors to capture two main focal points in just one shot, rather than having to shoot two different angles. 

Check out the latest episode of Shanks FX which shows you how to use this effect to its maximum potential.
