How to do light photography
There are many ways you can do light photography. You have to set the camera on a long exposure so you put the camera on a long shutter speed. Putting the ISO around about 100/200 not allowing much light in around the background. You can do it when you can see things in the background and have light painting in the image like in the video above. I had it where you couldn't see anything in the background and it was just dark. I had the settings on BULB, f.22 and ISO 100/200. There are many techniques you can do light painting photography. It is really fun to try out and experimenting.
