In the words of Blue Peter...Here's what i made earlier!

If you watched Blue Peter as a kid, this'll be pips, so no worries it doesn't take very long and it’s rather easy.
Most of the stuff you can find easily round the house.

What you'll need:

• a light proof container
• some black/ black paint
• tin foil
• tape
• a pin
• photographic paper

Starting with the lightproof container, i used a cardboard box, but you can use tins, opaque plastic containers, anything that won't let in light and preferably has a lid. But don't worry you can make a lid if you want.

What I did...

With a scalpel and ruler I cut a small square sized hole (about 3 x 3 cm) in the lid of my box. Then painted the whole of the inside of the box, (lid as well) black with matte poster paint. This was so that no light could get in and that there would be minimum reflection; to ensure this the box had to be painted a few times and black gaffer tape was used to cover up any patches the paint didn’t cover.

Once dry and completely covered, a piece of foil was taped onto the hole with gaffer tape. This would act as the lens whilst the pin hole put in the middle of the foil would act as the shutter aperture.
Also a piece of black card needed to be attached to the lid so that it covers the piece of foil with the pinhole; this basically acts as the shutter.

With the lid on you’ve made a pinhole camera!
However it doesn’t work…

For it to work we needed to go into the dark room to put in the photographic paper as its light sensitive, so light needs to be exposed to it in a controlled manner.
Making sure to cut the paper to size to fit in the box as well as applying double sided tape to ensure the paper won’t move; the paper is put in shiny side up.
The lid is then taped on to ensure no light will get in.

Now I have a working pinhole camera… But how does it work???
