The
difficult part for me to photograph the shrimp(Odontonia katoi) in a purple tunicate
is focus. The size of this kind of tunicate is around 5cm, and how much smaller the shrimp living inside is. Thus, I have to be very close to the tunicate since
I use Panasonic 45mm lens plus FIT+10 and FIT+5 diopters underwater. The siphon
of a tunicate closes easily when something approaches to it. The third picture
below was taken before the siphon closed totally.
In
order to take a clearer and more complete picture of the shrimp, I waited there
and tried not to have too much movement of my camera. When the tunicate felt no
more threat, the siphon opened again. I adjusted the focus and took some shots.
For
lighting, I placed two strobes on the both sides of the tunicate. In addition, I
set a FIT 2400 video torch in front of the tunicate.
