You might be surprised to learn that the photos below were taken completely in the dark.
This is possible, when you paint with light!
Painting with light requires a tripod, because you’ll have a very slow shutter speed to capture any bit of light within the frame.
Your ISO should be around 200 and your f stop f/11. Your shutter speed can be as slow as 30 seconds.
Flash your light on the subject and automatically focus. Then after you turn the light off, turn your camera on manual focus or else your camera might keep trying to focus on an object that it cannot see.
Once you begin taking the photo, flash your light around the object very quickly. You don’t want light to leak, so make sure you turn off your flashlight before taking it out of the frame.
If you have a metal object, be careful to not flash too might light on it. With some photos below, I had to flash the light around the object so the metal wouldn’t be blown out.
