Development of timestacks- faces

This was an experiment to see if I could develop my time stacks with something other than sky. I did this a while back with myself and a timer to experiment with how time stacking worked and how to achieve it in photoshop. I got another student to help with this experiment.

This was taken when my subject was rotating on a spinning chair. I have edited it similarly to how I edit the sky time stacks. I used flash due to the lack of light which had the effect of illuminating the subjects nose. Consequently you can see a trail of noses slide across the subjects face.

This was taken when the subject was rotating his head in a circular motion without moving his body much. This resulted in a complex view of the subjects face. He has many eyes dotted around his face. Using flash again, this added a bright glint in the subjects eyes.It also looks like the glare in glasses in his eyes, but he didn't have glasses on. This made his eyes more predominant in the picture which made it so the eyes more visible when they were blended . I also can see many other face. Such as the subject himself, and old man, a bold man. Which is a different effect to the other picture. 

I think that this is a very obscure use of time stacking. I won't do a whole shoot on it but it has been a useful development in the use of time stacking.
