"Himebotaru" is a small firefly about 6mm long living in the forest. On a summer night, they fly with light. I have been researching the firefly habitat for seven years and taking pictures. The shooting location is 10 to 30 minutes by car from my house and I shoot every night in June and July. All photos are taken with a single shutter and are not composited. I use 3 to 5 cameras at the same time. A shutter with a timer function is attached to each to shoot automatically. And I just leave it to Himebotaru.
