Xiao Jingteng has a song called "Stone That Will Hurt", will the stone hurt?

Yes, the stone will not only hurt, but it will also cry!
This may sound a lot like a romantic fairy tale or love song, but it has recently appeared in Okayama City, Japan.
For some magical reason, coupled with the photographer's superb photography skills, the beach and the seaside stones here are full of blue light and shadow, looking like they are in tears.
The two photographers named the group "Weeping Stones", how did such a fairyland-like photo come about? Wouldn't it be PS? In fact, this is a completely real photo, but it only requires a little bit of photography skills.
The photographs were taken with inspiration from a creature called sea fireflies (ウミホタル) on the Pacific coast of Japan.
As the name suggests, the sea firefly is the "firefly in the sea", a luminous plankton, generally only 3mm long, usually living in the shallow sea beach, every year from May to the end of October will emit brilliant blue light.
When stimulated, it emits a basket light and lasts for 20-30 minutes, when the blue light on its body is about to go out, the sea water can shine again. Usually, they float on the surface of the sea with the rising tide and setting tide, making the sea as brilliant as the Milky Way.
Sea fireflies are nocturnal creatures that forage on the shore at night through high and low tides, but how can you catch these sea fireflies? The photographer asked the local fisherman and took a measure.
They use small glass bottles that Japanese usually use to drink sake, put a little bit of these sea fireflies' favorite ham, and put these bottles in the sea for 40 minutes to an hour, and many sea fireflies will gather in the bottles.
Then these sea fireflies gently poured on the stone, press the camera's delay shutter, be sure to delay the shutter, so that the route the sea fireflies climbed will leave a blue mark.
When the tide rises, the little ones are back in the sea with the waves.
Isn't it a beautiful and sad photo?
