Tech Tip: Fluorescence Silhouette Photography

Put a non-fluorescent subject in front of a fluorescent background and what do you get? A silhouette that can have remarkable detail and make a striking and novel image. The photograph below is a great example of this. NIGHTSEA contributor Wayne MacWilliams captured this brittle star against a green-fluorescent coral while diving at Deep Blue Resort, Utila, Honduras.

This silhouette technique is another dimension of fluorescence photography that can reveal fresh views of familiar subjects.
