I like doing heavy edits to rescue photographs that didn’t work out for a variety of reasons, its fun and also a nice way to learn limits of what software do and how things really look.
The photo was taken on my smartphone and edited in Darktable, and in this case it is also prepared to demo some techniques and for once the work file is well organized. Due to low light conditions and handheld (not to mention nervous cat) it was severely underexposed and not very well composed.
Maybe a touch overdone. RT conversion just messing with lightness and contrast. Sharpened heavily in Fotoxx from tif. Saved cropped jpg. The sharpening cleaned it up a lot. Then the gimp. Duplicate layer - gaussian blur, layer mask to let the cat back through. Then wavelet decompose duplicated 2 layers at 50% opacity, both fur detail. Reduced and sharpened.
Ed Catmull: Quite a significant person in the evolution of imaging and graphics. I got to visit NYIT and The Graphics Lab in the late '80s, after he’d left for the other coast. They had done the first commercial 3D animations (CBS Sports), and were working on the first demonstrations of graphics acceleration hardware. Looking back on it, we were regarding some of the vision and thinking that is now ILM and Pixar…
Watched the movie “Incredibles 2” recently, and I saw something that I think might be homage to him. In one of the montage scenes of ScreenSlaver’s tech, I saw an interpolation graph, one that looked like what the wonks plot to illustrate the interpolation algorithms we use in things like image resizing. Mr Catmull had recently announced his retirement, and I began to wonder if this fleeting image was some sort of “Easter Egg” tribute to him, through his catmull-rom interpolation algorithm contribution. Thing is, I haven’t had the time to work through the math to see if it produces a similar plot. Anybody else see that image in the movie?
Edit: Slow afternoon, copied the catmull-rom interpolation function out of my software, put it in a little C++ program, and made the data to plot it. Here’s what you’d be looking for in the movie:
