Outback Print recently introduced a new Printer Evaluation Image. First off, a special thanks to Bill Atkinson for allowing the use of many of the image frames from his original test image. Since we already know from experience what to look for, it would have been akin to a re-invention of the wheel to create a test image with different image patches.
Best dive sites for Nudibranchs "Nudibranch hot spots" Here are some excellent dive locations for sea slugs and nudibranchs. Garry Cobb does lots of branching here Australia has more great nudibranch sites.

The 2 rhinophores of this white Dorid nudibranch are on the left, sticking up like antennae. The skin covering the top of the dorid is called the mantle, which is this case is covered with small bumps. Aeolids have oral tentacles, rhinophores and cerata. Some Aeolids can store nematocysts in their cerata, after they eat a Cnidarian such as a hydroid or anemone.
In this Aeolid, you can see the two large oral tentacles in the front, and the two smaller rhinophores sticking straight up on top of the head. The brown cerata cover the rest of the body, flowing backwards in this photo. Some nudibranchs can lose their cerata when harassed.
Nudibranch Natural History Most nudibranchs feed on only a particular hydroid, anemone, sponge, bryozoan, or tunicate. Underwater photographers often find a nudibranch by locating it's food source. Some nudibranchs that eat hydroids or anemones can store the nematocysts of their prey, using it for defense later on.From the beginning, both sociology and photography worked on a variety of projects.
Among these, for both, was the exploration of society.

Photography is the art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic rutadeltambor.com is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art.
