My first camera was a Kodak Brownie which took some very good pictures. I’m going to try this but need to read up a little more though. Thanks. Brings back some awfully good memories.

Thanks. Question for you…You mention that the focal length is 75mm however you created the base at 83mm. Is there a formula for this? I am planning to build an 8×10 box pinhole and I’m uncertain how to measure the base for an ~210mm lens (and also looking to design a 90mm focal length for the 4×5). If This is great! Thanks.

It gave me the incentive to finally get off my duff and make 4×5 camera, instead of succumbing to “temptation” and ordering a pre-made one. The directions could hardly be clearer, although I modified the plans slightly (changed the focal length to ~30mm for an extreme wide angle image and added a second layer of foam core to ensure that all edges were light-trapped and make it slightly stiffer / more durable for long-term use). Can’t wait to take it out and make some photographs—have two series of images in mind that I’m just itching to get started on! Thanks again! —Kevin Thanks for posting this article.

How is possible to buy it ? Thank you in advance. Regards. Good morning, I would like to try to produce the camera, I need to know exactly what kind of material is the matte board.

Kathia – f stop is the distance from pinhole to film divided by the aperture diameter – thus my 120 mm 4×5 camera with a .4 mm pinhole is 120/.4 or f300. You can use a scanner to measure the diameter of your pinhole. There are also relatively inexpensive magnifiers with measuring reticles available – check out the Peak Optics website.

In fact when I try to convert from the pinhole size to F/stop. Can you give a hand on this? thanks , kathia Good article Earl; I build my own 4×5 few months ago, and I have problems measuring the pinholes.
