I can’t measure sub-pixel camera movement at the sensor, so I have to look for indirect ways to get at it. Are there ways to glean such information from photographs of the ISO 12233 target? I turned to a simulation study to find out. Using Matlab, I created a nearly-ideal camera with a resolution of… [Read More]

I’m looking for a way to do shutter slap testing with sub-pixel sensitivity without spending a lot of money on variable intensity LED Fresnel lights. It occurred to me that I might be able to get what I need using neutral density filters to compensate exposures for different shutter speeds. Before I get started with… [Read More]
