Pinhole Camera

In photography we created pinhole cameras which are pringles cans with a pin sized hole to take the picture and we made it by getting the pringles can and then spraypainting the inside and then taking a picture with it. We spaypainted it black do that way no light can get in. There is a shutter which we use to open and close the hole so it could take a picture. The kind of image im making is a negative image.
