Making of 'Korallenblock': Both pictures were made at the same time with different cameras and settings. They are shown here as they came out of the camera. The picture on the left is from my dive buddy with his compact camera, no flash and automatich exposure settings. My coral photo on the right is made with my Nikon D200 and every setting manual: shutter 1/250s, f-stop closed until the sun doesn't get too much overexposed and both strobes full on to brighte up the foreground and get the intense colour. The water gets the deepest blue if it is underexposed with about a half or one f-stop. The metal stick in my hand (photographer antenna) is not used to provoke other animals as some other photographers may do. It is used to hold my position so that I don't touch something else or destroy it by accident. Photo on the left © Mr. P.
