Macro

Using a quality diopter of +10 or greater will dramatically increase the size of very small subjects and allow you to fill the frame with very little cropping. These Castosiella kuroshimae are miniscule and nearly impossible to detect. Look on small algae on sandy dive sites.

Mimicry is another behavior that an entire article could be written about, especially with these amazing Lobiger sp. Sap suckers live on algae that resembles green grapes. This image was shot in very shallow water in broad daylight. Using a high shutter speed will enable you to control the incoming light, even on the sunniest days. When a subject is tall, try turning your camera to the portrait position.

Showing nudibranch symmetry works well, like with this shot of a Nebrotha kuberyani. I particularly like to shoot these guys because of their interesting facial features, texture and vibrant colors.

If there is an anomaly of some sorts that sets your subject apart for the norm be sure that this anomaly is the center of the viewers’ attention.

The Miamira alleni is the holy grail of nudibranchs and is considered to be one of the most unique nudibranchs in the world. Lighting them is a tricky proposition as they have so many nooks and crannies, be sure to take your time and don’t be afraid to move your strobes to the right position that allows just enough light on the subject without creating too much light in the background.
