I took the picture with assistance of a special guide,subject was not seen by naked eye,he had to use a magnifying glass.
after spotting the pygmy sea horse I started taking pictures,with my Nikon D 300, 105 f 2,8 macro lens, with 2 strobes (ys duo ttl) maual mode,f 32,1/60.
focusing was also done manually because the subject moved very often and changed places almot continually.
we had to decompress 6 m 6 min,and 3 m 25 min!!
but from app 50 shots at least 2 were good!
