I wanted to submit this image to give credit to the main characters on these sets of images. Lauren, a real swimmer and fluffy, a real duckling whose patience, hard work and good spirit were invaluable. Real friends. Disclaimer: No ducklings, fish or swimmers were hurt in the process of taking these photographs. Large plexiglass tank. 7 feet white parabolic umbrella above at 45 degree angle inverted and covered with diffuser to soften the light even more.
