I had a brilliant idea to use
dinoflagellates (bioluminescent
plankton) for water droplet photography. The dinoflagellates glow when
stimulated (i.e. shaken, dropped, impact each other), so I figured they could
be used for a unique water drop photo. However,
there was a problem, while I could see the glow of the dinoflagellates; the
camera senor even when cranked up to ISO 6400 could not detect the glow at a
useful shutter speed to freeze the water drop. Usually when I do water drop photography, I
am somewhere between ISO 100 – 400 with an aperture of F4 - F8 and shutter speed of
1/250 or faster. When using the dinoflagellates I was at ISO 1000 – 3200, with
an aperture of F2.8 and a shutter speed of 5 seconds or slower just capture the
light the dinoflagellates produced. Thus,
I could not freeze any drops, and the resulting pictures look more like blurry
atomic partial traces or abstract art.
Below are a few of the better images after they were edited to get rid
of grain and artifacts.

| ISO 1600, Aperture F2.8, Shutter 5 seconds |
i am sure you will be able to figure out how to take the pictures especially if you can see the electric interaction with the naked eye. i am sure your final result will be interesting to medical research.
