In a darkened room, simply paint around your subject, while you hold the camera shutter open.
1. Best done at night, so you can get the room pitch black. Close the curtains and then set your arrangement up before getting ready to switch the light off.
2. You then need to put the camera onto the B setting, so that you can hold the shutter open for a required length of time. Select an aperture of about f/11-16 just so that everything is in focus and also so the exposure is long enough to do some painting of the subject.
3. Using a torch move it around your subject, keeping it moving throughout the exposure to avoid hotspots.
4. Check the LCD screen and adjust the next exposure to increase or decrease the exposure.
