A fourfold exposure - quite under the influence of the wish, to make it look like being under some intelligent machine the reactions of which are not predictable. So, imagine standing under its camera-eyes that see all, being spoted by its lights, and you don't know what it's going to do next. Very uncomfortable! ;-)
many thanks for the nice and detaield comment, Urs! It seems that sometimes there is enough to capture even at the railway station of Lucerne. ;-)
I think that the trick, if one may name it so, is mainly the slight bottom up perspective "enhancement" of the main exposure at a focal length of 28mm. The other three frames contribute some "decoration" by adding the diffuse lights, etc. at the "head of the robot". Or so I thought. :-)
Great composition! Even withoutyour suggestions,I like this picture very much. :) Although, in relation to your story I would say, you tricked this camera out! :) Well done, congrats.
