Mimicking Neutral Density with Stacking

A look at how to mimic the results of using a traditional optical neutral density filter on a digital camera with repeated captures and mean stacking in post production.

Building a Hyperbolic Resolution Wedge in Illustrator

In another article I described and made available my camera acclimation target. In the process of building that I ended up having to sit down and build from scratch what I’ve frequently seen described as a hyperbolic resolution test wedge. If you’ve ever used an ISO 12233 resolution chart, or looked at the resolution charts […]

Preliminary testing, Diffraction Correction in Digital Photo Pro

In my article about re-evaluating my position on crop cameras, I mentioned that a 20MP crop sensor was diffraction limited pretty much right out of the gate with the f/5.6 lenses that make crop camera setup appealing to me. When I said that, I knew full well that one of the biggest advantages of digital […]

Performance Aspects of Exporting Video with Premiere Pro CS6

The question has come up a couple of times in my article on enabling CUDA support in Premiere Pro regarding why exports still take so long even with the GPU enabled. The reality is that while Premiere Pro does use the GPU for rendering exports, the process is slightly different and the results can be dominated […]

Photoshop Smart Object Stacking for Noise Reduction

Stacking images to improve the single to noise ratio is a tried and true technique in astrophotography. The typical noise reduction most photographers are used to uses sophisticated algorithms to attempt to smooth noise out without smoothing out fine details in a single frame. Stacking exploits the randomness of noise and the consistency of actual […]
