The $3.00 Cigar Box transformed into (I hope) a working pinhole box camera.

I used Scotch brand electrical tape. Hence the logos !!!

The pinhole is 0.5mm.
The distance from the pinhole to the film plane is 85.7mm.
The approximate "f stop" is f170.
The image (cone) circle is (maybe,) 162mm or about 6.4 inches.
In theory, I should have coverage over the sheet of 4" x 5" film.
Watch this space. :-)
