Things You'll Need
Instructions
Place a piece of thin colored plastic over your camera's flash. Draw a stencil in the shape of the flash onto the plastic using a marker. Draw another stencil around the first so that there is a finger's width of space between the two drawings.
Cut the outermost drawn stencil from the sheet of plastic using a pair of sharp scissors.
Place the plastic stencil over the flash; it should be slightly larger than the flash on all sides. Fix the plastic to the flash's body using a rubber band. Try to avoid creasing the plastic, which could result in uneven lighting in your photographs.
