Hi all - here are a couple of dodgy photos of mine of a male Cardinal fish with immature eggs in his mouth.
Shot with the OMD EM-5 & 60mm macro lens in the Nauticam housing with twin YS 110A strobes.
F8 @ 1/160 ISO 200 and strobes at 2/3 power - unfortunately the visibility was only 4m and very milky so it makes it difficult to get a clean shot.
Those are very nice, the eggs are well lit even though recessed. Were you using a single strobe? Also nice work getting a front view of a brooding fish.
Nice captures, try to shot with bigger F Numbers it will darken the background.
