No photoshopping - just good old photo of a place where my left hand was just a few seconds ago.
This is a fun photo experiment with a time delay. In some circumstances, with careful preparation, you could take an image of something that is not there anymore. It is not too hard. Just make sure that you have a nice and quiet place, good light to show all details, and enough flour to leave an good imprint (more than 40 pounds in my case). :)
