I didn’t end up using the digital camera (Canon 60D) as much as I thought I would. Most of the shots with the Bell+Howell, I winged it.
The conversion was pretty straightforward — The metal pinhole from the cardboard camera from last year taped to a T-mount lens adapter for the Canon. I only used the needle to make sure the hole was clear and clean of cat hair.
My favorite shot from the Canon. I think the pinhole is larger than necessary so the kit will give something to a kid using the Ridley camera.
