Pinhole photography
Some pinhole cameras look homemade and some look like a real camera but they also can look like shoe boxes. The lenses of pinhole cameras may be punched or drilled using a sewing needle or small diameter bit through a piece of tin-foil or then aluminium or brass sheet. This piece is then taped to the inside of the light-tight box behind a hole cut through the box.
They make real images like how they was showed in the old time pictures, the different tools you might need to make a pinhole camera include:
black paint/paper
