We recommend practicing in front of a mirror or a camera first by slowly moving the iPhone until you find the right movement to use. Best results are obtained in a darker setting or at night.
The longer the message you input is, conversely the longer the shutter speed should be (in theory, unless you want to be creative !), also adjust the aperture accordingly.
For easily getting the best results we recommend a shutter speed of at least 2 seconds. Use a tripod for holding your camera is recommended.
