STEP 1: Get the camera settings properly adjusted (Shooting Mode, Shutter Speed, F-Stop and ISO), put your tripod in place, and get your light source ready. Now go ahead and frame the shot that you want to create this is best to do with the lights on; if you are in a dark environment turn on your light source to project light onto the scene so you can frame the shot.
STEP 2: Next you need to focus the image, if you are in an place where you can turn lights on and off TURN THEM ON FOR THIS PART. Zoom in as far as you can to the part of the frame you want in focus, if the lights are on you can use your auto focus. Once you have the focus set your lens over to manual focus and leave it there, now zoom back out and re frame the shot. If you are focusing in the dark set the focus on manual, illuminate your light source and place it in the shot next to the part of the scene you want to have in focus, zoom in, pull focus on the illuminated light source, leave the lens on manual focus, zoom back out and re frame the shot. This will ensure you get a sharp image.
STEP 3: Turn all lights off. Open the shutter of your camera to begin the long exposure, illuminate your Light Painting Brushes tools and begin to paint.
