Thanks for your comments. I'm glad you like the photos.
The pinhole camera was made by removing the lens. It was held in place using some sort of wire clip. I think I used a small screwdriver but it was quite a few years ago so I can't remember now. The pinhole was made by pushing the tip of a pin into a thick piece of foil - the sort which is used for pies from a supermarket or bakery. This was held in place using blu-tac.
To answer your other comments in the other post about the pinhole size, it was difficult to measure but I think it might have been 1/4mm or a similar size.
