I made a pinhole in a bit of metal cut from a can of coke, stuck it on a body cap and had daughter #1 hold still for 15 seconds. What did this prove?
1. It's hard to get a small pinhole. I used a pin, but I should have used a needle. A smaller hole would have produced a sharper image.
2. Any dirt on the CCD shows up after a 30 second exposure. I had to clean up at least 20 spots in lightroom.
3. The irregular bokeh (especially visible in the white background) means that my hole must be irregular.
