I think he's trying to make a statement with regards to the light. I'm still looking at the before and after since I just realised they are the same with more light in funny directions.
I mean, since he took the trouble, should be worth some time! =D
First one - I see a couple holding hands, well, headless couple, anyways.
Second one - two friends on each others shoulders, with one's head just in the corner of the light.
Fourth one - of all things, Porky the Pig from Loony Tunes. I think if this was a Roscharsch test it'd reflect a deprieved childhood or something already.. =D
Third and fifth can't see! What do you see, eikin? =D
