The photo below is a close-up look at the tube feet of a sunflower starfish (Pycnopodia helianthoides) as it crawled on the inside of a glass aquarium. I took the picture over 20 years ago and recently had the original Fujichrome 50 slide scanned and digitized. As always, the scanned image needed some work (you can see the unedited version on my blog). This is the final result after editing with Photoshop and Noiseware.
