Anyone know how to make a simple pinhole camera?

All items have now been ordered! Just your link to the lamp was not working, it kept linking me to the fixed. Which lamp did you suggest?

No longer a pinhole, but almost. You can also use a drop of water as a "macro" lens in such a camera. Distilled would be the ticket. And the drop could also be any other clear liquid (as long as it does not evaporate too readily). Experimenting would be needed for the focal length. But it will shorten drastically.

Just a comment.

We used to have two photo shops in our town. One has closed down,  and the other no longer stocks the chemicals and papers.

So,  apart from the run of the mill stuff from Max Spielmanns,  anything else has to be ordered via the net. 'Monochrome film ?  Sorry sir, never heard of that'.

Yep,  it's a digital world out there.

Chris,

Just a few more notes on camera (box) making.

For the plate for drilling the pinhole, the thinner the better to block as less as possible light that comes in angle (from up, down, left and right). You may have on your shop some shim stock that could be really thin. To drill a clean hole on shim stock, clamp the shim stock between two 1mm aluminum plates and drill it.

The deeper the box, the larger the formed image on paper will be. A 20cm deep box will produce a good image size for on the 5x7 paper. What you will get is a round image on the center of the paper. A 10cm deep box will produce a smaller image.

Use black matte paint inside the box to avoid any light reflection inside the camera. Maybe you can make the door (to load the paper) so it fits the box with steps to avoid light to get in. Black thin foam is also good to make the door light-tight.

Do not paint the pinhole plate, as paint will make it thicker.
