Multi exposure with mask
Here’s a photographic experiment and attempt to compact more information into a single image. What it is, is 9 separate shutter activations on a single digital capture with a mask in front of the lens that I moved for each exposure. The mask was a narrow aperture that I moved from left to right as I panned slightly from left to right for each shutter click.
The ability to capture in this way has been a feature of both my Pentax K10D and K-7 although I’m not sure that this is what the engineers intended.
