On the Cover - Photo donated to DAN by Adam Sokolski

Equipment Used: OM System OM-1 Mark I camera with a 90 mm macro lens in a Nauticam housing, paired with INON Z240 strobes.
Location: 
Romblon - Philippines

This photo features Cyerce nigra, captured in the vibrant waters of Romblon, Philippines. These delicate sea slugs are often in motion, and when they move, they undulate their entire bodies in a fluid, almost dance-like way. This constant movement makes it quite difficult to capture a sharp, well-composed image, especially in underwater conditions. I spent a long time observing its behaviour and patiently waiting for the right moment. After numerous attempts and careful timing, I finally managed to capture a shot that truly showcases the beauty of this fascinating creature.
