Its actually pretty easy all you need is these three things
- A camera. ( not a fancy one just the one which are able to manipulate shutter speed.
- A stand. ( MUST HAVE, you don't want to have your background gone blur and still maintain long time for drawing.)
- A LED light. ( more color/colour ( british and american spelling) more beautiful )
So here's the trick by setting for longer shutter speed you are enabling your camera to capture more light, but here the things since longer shutter speed, your camera will be more sensitive to motion. that's why you require a stand to reduce the motion. So try it out. Experiment your life.
