How to shoot light painting in Canon 100d? How to adjust the shutter time

Light painting, as its name implies, is to use light to express the pattern you want to express. So there are several premises:

1, dark or dark background

2, a relatively bright light source or theme, to paint.

3. Enough shutter time to finish painting, which can be about 30s or longer. But you should know that the longer the exposure time, the easier it is to overexpose, so the dark background is still very important.

Summary: Set the camera to m, set it to a small aperture such as F 1 1, and have enough shutter speed such as 30s. I hope you can succeed.
