After three months in the desert a visit to the North Carolina Aquarium on Roanoke Island offered contrast and rest. My son and his wife were visiting, and with his Nikon Coolpix I made a series of exposures, keeping the lens close to the glass to eliminate reflections. Opened and saved in Nikon Capture One, converted to black and white with Silver Efex Pro 2 to preserve the dance-like quality of the creatures' movements.
