Often scanned images have a tendency to look “washed out”, and the Samuel In Dolgnwot pictures are no exception, as can be seen in the scanned version of series two, episode three.
I have been manually attempting to fix this with some tweaks to the brightness and contrast, which works to an extent.
However GIMP has a most useful feature which is designed to fix up the colours on scanned images automatically (it can be found under “Layer–>Colors–>Levels” and click the “Auto” button (Yes, I know, American software with American english). It does an excellent job.
I have now gone through and fixed up all of the Samuel In Dolgnwot images, and as such, they are now much more like the drawings, and much more lively.
