I made a pinhole camera from an iPhone box by drilling a hole into the centre and sanding it down. There was no need to blacken the box using paint spray as the box is already light tight. I cut a square piece of a Coke can and with a sharp needle pierced a small hole - the smaller the better - and sanded this down so there were no rough edges. I stuck this on to the inside of the box in the centre of the drilled hole with black electrical tape I put another piece of electrical tape on the outside to cover the pinhole - my shutter.
More tips on how to make a pinhole from Youtube link below.

- Always take the photo outside and on a day where the light is contstant - make sure the sun isn't shining directly at your pinhole.
- A pinhole gives a wide angle so go closer to the subject.
- Don't hold the camera as it won't work - too much shake.
- When you get a print and are looking at your negative if it is:
- Too dark - was exposed to too much light
- Too light - wasn't exposed enough to light (or you put the paper in the wrong way, just don't admit it !!!)
- Streaks - possibly a light leak.
- Blurry - camera shake or the pinhole could be too big for the focal length of the box/camera (the focal length is the distance from the pinhole to the opposite side of the box/camera).
- To make a positive image from the negative put the photographic paper glossy side up and place the negative face down . Put a sheet of glass over the two so that they are flat and in direct contact with each other. Expose to white light. If the image is:
- Too dark - was exposed to too much light
- Too light - wasn't exposed enough to light (or you put the paper in the wrong way- and AGAIN just don't admit it !!!)
