Also taken in my Studio Lighting class these are pictures from two assignments; background lighting and silhouette shooting.  The first picture was from the background lighting shoot and also I experimented with a long exposure while having the subject move.  The background is blue and the assignment was to experiment with the different colored gels that were available to us and put the on different strobe or hot lights pointing them towards the background to create any colored backdrop we wanted.  The bottom two images are from a shoot where we had the model sit directly in front of a light so that their face or body was blocking out the light towards the camera.  In doing so there is only a minimal amount of light that reaches the lense and therefore creates this silhouette of the light from behind the model.  Depending on what position you were in or if you moved around the model, you would get a lot more light or no light at all.  The silhouette shoot was most interesting to me because beforehand, I never knew how photographers created that look and it ended up being such a simple set-up.
