I am very pleased. This was the first try at it, and I didn't really know what to expect. I just knew that I wanted each exposure to be a reaction to the preceeding exposure and what I see as I move the camera.
I build the highlight densities over the course of three or four exposures, while trying to keep the shadows as dark as possible. The real hard part is remembering where all the elements were placed in the first exposure.
Everything is built on the first exposure. It is also difficult to know where to stop. Often the last exposure of one picture leads to the first of another picture.
