Photographer: Rob Gilley
Subject: Red Tide
Location: Carlsbad, California
Specs: Canon 5D Mark II; 28mm 2.8; Approx. 5-minute exposure
Comments: "It wasn't until the late 2000s introduction of ultra-low light sensors that a phenomenon like Red Tide could properly be captured. Previous issues with reciprocity failure and long exposure motion faded away, and allowed for new possibilities."
