Photography problem, how to take better fluorescent photos at night.

This depends on your camera settings! With M, set your shutter to B (long exposure), and then prepare a tripod, preferably wired release or remote wired release. The combination of aperture and ISO, shutter, this is hard to say, it depends on your own actual operation. You press the shutter, then run with the fluorescent lamp in your hand, and then press the shutter later to finish the shooting. The effect will come out, but it still depends on your own actual operation.

I'm just explaining the steps and methods I'm not very detailed. If only I could teach you with my hands. For your reference)
