Sorry, again a “Nerd Show”. I tackle some problems that have come up with the Python script of the last week and show my way to debug and test while making errors. My first error was to take a test case without colours – my script from last week changed all images to greyscale. Then I learn something useful about merging layers in Python.
The scripters crowd in the forum found a bug in GIMP, saulgoode reported it and it got fixed in a day. Take that, Adobe!
Then I try to explain why the big blobs in the image featured two shows ago are not made with GIMP but with pure physics in the camera. You can see a Blender video I made about this for #200 of Chris Marquards Tips from the Top Floor show. My part starts at about 11:40 and contains an embarrassing error. Do you get it?
The next show will be a simple, non-nerd walk through the post processing of an image. Promised.
