Dr. Greg's Historical & Modern Photography
I started about 60 years ago on film. Back then it was 620 and I processed the film in the basement of my parents' house. I still believe it can be truthfully said that the majority of my photographic work was done on film.
Over the years I have experiment with film and how I could use it. The multiple exposures here were all done on film, before PhotoShop. At one point I fell in love with color film (mainly negative film) and experimented with multiple exposures on the same frame using sharp-cut filters. I also experimented with multiple exposures using a figure moving through the frame or partially exposed in the same frame. Since color film has three emulsions it provided me with what proved to be a rather serendipitous experience. I never could be sure of what was on the film until I developed it!
