I have found that, for macro work, once you've setup your lights and white balanced, I then go into the camera settings, to the exposure setting, and knock it down a couple of steps. It has been making a huge difference.
Here's a clip from last week, of another nudi, this time eating a shrimp. This was taken in very tricky light conditions, about 5m, sunlight coming through the water surface, light coloured muck on the sand, but it came out very very well by knocking the exposure down. I highly recommend this when using Sony camcorders. I now need to re-film everything from the last two years!!!
These large nudibranchs are carnivorous and have a great way of feeding.
They throw their 'head', an oval veil, in front of them, and using hairs around the edge, attempt to scoop up whatever they can find, usually small Crustacea.
You can watch this Melibe moving around, searching for food. About 2/3 of the way through you can see the Melibe captures a small shrimp in it's mouth and then holds it shut until the shrimp is, presumably, devoured!
