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.” This photo was submitted to Your Shot, our storytelling community where members can take part in photo assignments, get expert feedback, be published, and more.
