Cat Tracking _ Test Photo 1

Cat Tracking _ Test Photo 1, originally uploaded by mdshaub.

I compiled all the frames of the video of my cat wearing an LED marker into a simulated long-exposure photo. The original video frames were processed to only include the LED marker on a black background.

AfterEffects was then used with the Time Echo filter to overlay all the frames of video onto each other.

The LED light is colored blue at the beginning of the video and shifts to cyan by the end. I'd hoped that this would make it easy to trace the motion over time but with the over-exposed areas looking cyan as well it is not perceivable.
