Got stuck on the train a bit longer than normal today (heatwave signal failures) and added hexagon culling to the digitizer.

So this..

Now my favourite processing from the last post looks like this (which I believe is an improvement).

If you look carefully, any sub-hexagon that does not contribute to the detail is culled, this results in an interesting effect and in the end is exactly what I was after. Some contrast is lost, but I think that’s a given seeing that I am applying an exotic ‘blur’. I’m going to generate some colour histograms later and see what spectral distortions I might be adding.

Here are some runs against some default the sample Windows ‘photos’.
