Okay. I made a very simple pinhole camera. Am I right in thinking that a smaller hole will make a sharper image? I didn't find the smallest needle I have so will search for a real tiny one!

The negatives were really light so I'll have to leave the pinhole open longer?

Fun to make. I think that this will be a great project for my photography kids. I'll just have to practice a bit to make sure I can get a good image before I show them.
