Halo Effect

Bioluminescent phytoplankton surround swimmers in circles of brilliant blue light. Your Shot member Will Strathmann captured this image while in Krabi, Thailand. “[I] heard that the bioluminescence [was] beginning to peak under the new moon … While this photo doesn’t come close to the actual experience, I am proud I was able to capture and share this magical moment.”
