I photograph wild Indian ocean bottlenose dolphins in Mikuraisland, Tokyo, Japan.
After rain, the surface of the sea becomes muddy and visibility becomes poor.
However, if you dive a little deeper, a beautiful layer of water may appear.
When the sun shines through the muddy water layer, the streaks of light become clearer than usual, and it is very beautiful.
Dolphins were swimming around the boundary where you could see such a beautiful light gradation, and it was very fantastic.
In this area, both scuba diving and strobe use are prohibited for the protection of wildlife, so I took pictures using sunlight during skin diving.
