space and time

- since it is raining here and spring took a break, I decided to use the time for some experiments in photography.


This shot is in reality 45shots. Taken at munich underground-station marienplatz during a period of about 90 seconds. The camera is not the fastest one... During this period, the train rushed in, people unloaded and loaded, doors closed, train rushed out. Took them freehand, no tripod, as always ;))


Next I took a little time. First I aligned the shots with Hugin automatically. In Gimp I reduced the 45 initial layers to 15 layers by adding 3shots to one layer with "add" function. This also compensated my slight underexposure of the single shots.


The resulting 15 layers were then alternately added and subtracted. This preserved the impression of the moving people. To get 3 Exposures I varied the parameters of adding and subtracting.


Next step was to make an HDR from the 3 Exposures with luminance and tone-map the result back to LDR.

Finally some tweaking on color and contrast with RawTherapee.


And thats it. Killed 3 hours and the result is ... hmmmmm.... at least interesting.

I think I wouldn't do this very often... too time consuming..... so don't worry if you don't like it.


Apreciate your comments and critics - so feel free to tell me what you think.
