Pin-Hole Camera Workshop

Kayleigh Kendall recently held a workshop where we all created our own pinhole camera. I decided to make mine huge to see if it had a knock on effect on the display's size ad clarity, however I have yet to see if it works.
On one side of the box, a completely opaque side is needed (black card) along with a very small part of the side made of tin foil where a small pin hole is punched through. On the other side is grease proof paper so the image may be displayed upon it.
The light travels through the pinhole and is displayed upside down on the grease proof paper.
