Also how to have one person appear twice in a photo graph with out editing the photo
A Camera (One that can has a blub setting or can do long exposures)
Lights (I perfer LED's but it all depends on the picture you want)
Flash (Optional depending on the photo. Must have a flash for the second half on the instructable)
Step 1: Find the correct setting
For my camera the Canon 10D all I have to do is change my shutter speed to BLUB or have it be longer then 1/20th of a second (The Shutter speed also depends on how much light you want to allow in. If you want to "draw" a lot with the light then set your camera to a longer exposure setting, if you want a smaller "drawing" set you shutter speed faster. Its all about experimentation though, so mess around a little)
Point and Shoot:
All Point and Shoots are different look up in your camera's manual to find out how to set your cameras shutter speed. If there is no way to do that by your self try covering up the lense with you hand and turning off the flash. Focus and meter dont click the shutter yet. Once the Aperture and focus has locked remove your hand and take your picture. It should of set your shutter to the slowest it can since your hand was over your lense.
