This is a picture of long exposure of fluorescent algae on the beach. Of course, this is not a wonderful picture

In fact, although it is the 13th day of the lunar new year, the moon has long been covered by thick clouds, making it so dark that you can't see your fingers! Without any light supplement means, I have been using 20 to 30 seconds for long exposure. At this time, my sensitivity can be set at about 400

Maybe due to my photography level, the picture in the camera has not been what I want! When I was distressed, an idea suddenly popped out of my mind. Why don't I try a 900 second long exposure? I use Z72
