Another way to do light painting is by using other light tools than just a flashlight to paint your subject.
Learning how to use different light tools was so fun! We got to do the light painting as well as be light painted (hopefully that made sense). Anyways! The trick is to do have similar settings as light painting in general; ISO 200; f/11; 30″. Then instead of painting objects, you paint people and also paint using light tools.
To do both at the same time, you either shine the person first or last (doesn’t matter) for 7-10 seconds or so. Then use the light tool to create cool effects like these.
