This is just a short show to catch up on my missed show on Tuesday. I’ll look a tiny bit behind the math in the convolution matrix with a spreadsheet model of a single row of pixels.
And I’ll show you an often overlooked feature of GIMP – the screenshot. It’s way more flexible than just pressing “PrntScrn”. It even stores the mouse pointer on a different layer.
The companion file contains also the images for the next show. I was too lazy to un- and repack that again.
