Sooo I made my own tube for dipping my camera lens into the water. As some of you may know Water Refracts Light and makes it annoying to take underwater pictures outside of water. Gets blurry. That's why you have to be perpendicular to your subject when photographing something that's in water. Dipping your lens allows you to take pictures at any angle without refraction. Fidel correct me if I'm wrong. What's available MY DIY Project 3-inch PVC from Home Depot ~ 10$ Nylon Screws from Lowes ~ 2$ Tap and drill set from Home Depot ~ 10$ Circle piece of Acrylic from Tap Plastics ~ 3$ I used Gorilla Glue which most say is not reef safe....but I don't care. It's cured and I only dip the lens for a couple minutes. Future builds will use Weld-on 16 which works but not the absolute best for PVC to Acrylic bonding.
