Exercise: Multiple points

The exercise s to create a still-life and take a photograph of each step. I have taken a few series of pictures, but chosen this series of marbles as the light and reflections added extra changes. As each marble was placed the observer can notice subtle changes in the light and also changing reflections in the central marble. Each marble was randomly placed without having a final image in mind.

Images 4566 to 4573 where taken on 18.3.2012, 8sec, f29, ISO100, 116mm.
I chose a large depth of field to get all in focus, I hope. The scene was lit by a single table lamp.
As each marble was placed the relationships changed. At times the image was balanced or a bit unbalanced. The final picture forming a spiral originating in the centre and possibly continuing beyond the frame. At this point the series has come to a natural end.
