Customising my 5x4 superwide pinhole camera (here before I've modified it).

Here is my pinhole unaltered.

I've ordered some parts from Hong Kong on eBay to customise my 5x4 superswide pinhole camera. I've had to look up online for angle of view charts and calculate a hypothetical viewfinder of 100 degrees and inscribe it on the camera to improve composition consistency. I'll put up an image of it once I've modified it.
