Saltwater tank
A friend of mine asked me to come over and get some photos of corral in his saltwater tank. I was surprised at the myriad of species he had and how much I enjoyed shooting them. Obstacles included glass that was curved and scratched, and a minimal focusing distance. Luckily I still have a tube extension in my bag, which was used for 90% of the pictures.
that extension tube is pretty useful huh…
