The photos can be distinguished in too bright, too dark, with a lot of red (because of UV lamp) and good photos.
First we need to get rid of the too bright ones because they show nothing significant.
Later we may want to classify the other types for better time lapse videos.
- categorise some photos using shotwell into 4 ratings (named above).
- add some image manipulation functions to calculate hue.
- train using i.e. Tensorflow
- Profit.
