MAKING A 4×5 PINHOLE CAMERA FROM A BOX

I get a lot of empty boxes from people who know I make pinhole cameras. Lately there has been a bit of a backlog. One stood out head and shoulder above the rest. A Paperchase Kraft gift box 190x190x110mm. Strong, sturdy and just the right size to take a 4×5 dark slide.

To calculate the focal length and diameter of pinhole required, measure the distance from the film to the inside face of the box. Use the PaperCamera charts a to calculate the pinhole diameter, f-number and recommended exposures

Secure the lid to the body of the box. A quick coat of paint and you are done. My camera took about an hour to make and cost nothing.

My box camera has a f-number of around 200 and the angle of view should be about 90 degrees
