[Note Guidelines] Photographer's Note
here's another clear shot of an underwater plant illuminated by the noon sun against a muddy green background.
It was captured by a Canon point-n-shoot in an underwater case with the flash turned off.
My best guess for explaining why a plant would want to use red instead of green pigment for photosynthesis is because water absorbs red light most quickly, leaving little for a green leaf to absorb. However, if the leaf reflects red (as in this case) then more of the spectrum is available for photosynthesis. And I believe the molecule is called rhodophyll.

Hi John, nice underwater capture of this lily leaf. The lighting and colours are good with excellent contrast. The sediment filled water provides an excellent natural backdrop to this red leaf.

Thanks, John
