I am wanting to do some portraits with my plate cameras. It seemed only fair and prudent to first subject myself to the process.
I picked a corner with reasonably good light and propped a box up where I thought my head would appear. I focused on a barcode on the front of the box and then substituted my nose for the barcode. I made the shot using my longest cable release with the camera set to 1/2 second and f/22.
