The pinhole camera is made from tin box of aftershave, equipped by holder of instant film made of cardboard from boxes of chocolates, the engaged sided sellotape. Due to the price Fuji Instax Mini Film was selected.
I was a little afraid of developing film, which under normal conditions is carried out by sliding the exposed film from the body of an instant camera, but after reading some instructions on the internet [1] and two failed attempts, the difficulties were overcome with the help of smooth tiles and anodized tube.
