With the right flash, filters, and digital camera with manual controls you can take fluorescence photographs underwater or outdoors in the daytime or with the lights on indoors. NightSea founder Charles Mazel has just published a paper in the online journal, Limnology & Oceanography: Methods, describing the method for underwater use, its limitations, and strategies for making the most of the technique. You can download the paper directly, or read about it on the NightSea web site.  The paper describes how the technique can be applied in a typical laboratory or home environment, and contains example images.
