Long Exposure

http://www.denisolivier.com/artwork/gallery/detail/Ghost_opera/24

This an example of the effect of ghost photography, the work is title Ghost Opera by Denis Olivier.
The images were shot at long exposure and in these images, the subjects seem to be moving so the result is effective.
I like the last one on the right, it looks like the same subject , but I do not know, however it fits well with my doppelgänger idea.

I want to experiment with using long exposure combined with the contrast lighting I'm using and the make up to see what effect it creates. In the past I posted about my experimentation with food colouring to create a misty effect which I then thought to combine with green screen footage to create a ghost effect, but I shall try it with long exposure photography to see which give the best results. This will be done when I carry out my lighting tests this week.
