3-Dimensional Airy Disk Animation
Posted in Photographic Optics on Jan 8th, 2008
This is a 3-Dimensional Adobe Flash rendering of Circular Aperture Diffraction (an Airy Disk) forming. It is not to scale…and slowed a wee bit.

Sniffing Out Time Lapse Fraud
Posted in Photographic Optics on Jan 6th, 2008
Time lapse is catching on. Unfortunately we’re seeing some simple PTZ and NLE framing manipulations being presented as the product of motion control.
How Did They Do That?!? The Dolly Zoom.
Posted in Extremely Extreme Photoshop, Photographic Optics on Dec 20th, 2007
I’ve been asked by a couple of people lately about a cinematic technique that is evidently still in demand: The Dolly Zoom (or “Zolly”). The camera position is apparently static while the background zooms either toward or away from the viewer. OK…it’s pretty cool, but it’s old and busted (I think that means “cliche’”), and [...]
The Circle of Confusion: Recognizing the Limits of Human Visual Acuity
Posted in Photographic Optics on Sep 3rd, 2007
Our investigation of the balance between lens performance and sensor spatial resolution wouldn’t be complete without considering how we, the ultimate sensors, will judge the result. If there are physical differences between two imaging systems, are we able to perceive and evaluate them with our essential vision in customary and reasonable situations?
The Dawes Limit: Theoretical Limits of Lens Resolution

The Dawes Limit is the smallest resolvable angle of an optical system.
