A Pinhole Camera is a camera made using a light tight object and light sensitive Photo paper.
Firstly a hole is made in the object (i.e. tin or box) using a drill, then a square of foil is placed in front of the hole and sealed using gaffa tape, gaffa tape being a thick tape making the camera more light tight.
Next an aperture is made in the foil with a pin hence the name Pinhole Camera, A shutter should then be created to cover the aperture, a suitable shutter would be made from card and gaffa tape, as long as the shutter covers the hole it is suitable.
When loading up a Pinhole Camera you must use a safe light and ensure all doors are locked with no lights on else the light sensitive paper will be permanently ruined.
Tape needs to be place in the camera to make sure the photo paper does not shift once the photo paper is loaded in the light tight box or tin and it is sealed then it is safe to move away from the safe light. An F-stop then needs to be calculate for this you will need the focal distance (the distance from the aperture to the photo paper in mm) and the diameter of the pinhole which should be about 0.8mm.
Once you have gathered these two measurements a basic calculation is needed which is the focal distance divided by the diameter of the pinhole (i.e. 70 divided by 0.8= 87.5) this is your F-stop.
We then use the F-stop and light readings to calculate the exposure time (how long the shutter is left open) in my case the exposure times where 30 seconds outside and 5 minutes inside, the reason the exposure time is more inside is because there is less light.
Once the photo has been taken the camera needs to be taken to the dark room and unloaded.
When the camera has been unloaded the photo paper needs to be doused in developer for 1 and a half minutes then moved to fixer for a similar amount of time, after all of this the photo needs to be quickly washed and finally dried giving you the final product.
If your photo is very white it means the photo has be under exposed and if the photo is very dark it means it has been over exposed.

Some really pleasing images resulting from this week-long project George - well done. I also like the level of information you've included along side the photographs. More details of the actual principles involved in making photographic images however would have also helped the whole project.
