Using the Right Arms and Clamps in your Underwater Photography
The importance of good Underwater Photography Equipment
When I go underwater to take photos, I want my equipment to work, to be easy to use, and not cost an arm and a leg.
Back in 2006, after shooting with a point and shoot camera for a while, I decided to upgrade. Did I want a more expensive point and shoot with wet lenses and two strobes? Or did I want a dSLR?
After lots of research, I decided that I was serious about underwater photography, and I bought a dSLR with 3 of the best lenses Nikon had - the Nikon 10.5mm fisheye, 60mm macro lens and 105mm VR lens, all brand new.
I also got 2 strobes, 4 arms and a bunch of clamps. I placed my order on March 20th, 2007. Thinking I could save money, I bought from a company known for discount products.
This is what the saleperson wrote to me:
"They are very, very close to ultralight’s weight, equal in quality and half the price."
The person who sold me the arms and clamps is not a bad person, and usually had great advice. But in this instance he turned out to be quite wrong.
Now I'm not afraid of a bargain, and this company made one of the best lights out there imho, and they had other good equipment. I probably saved between $100 and $200 total.
But after just a few months, the clamps were completely froze up and not working. All of them. Cra*p! The rubber rings around the clamps were shot. I had to use 2 pairs of pliers to remove them from the arms.
I repurchased everything from Ultralight Control Systems, ULCS. Hundreds of dives later, the arms and clamps are holding up perfectly. My strobes are easy to move around underwater, and I can always get the lighting I want.
Don't underestimate the importance of good ergonomics in your strobe arms. I often adjust my strobes for each subject, and change between front, side and back-lighting.
It's nice finally having clamps that work
Here's my tips for choosing arms and clamps:
Buy high-quality arms and clamps that you last you for a long time. This is one area where it's not worth saving the money, I found out the hard way. (There are lots of other products where you can save money though!)
Get two arms on each side. I suggest an 8 inch arm and a 5 inch arm, with 3 clamps. Start off with one strobe, and add a second strobe if you an afford it. The reason for the 2 arms is so you have flexibility for moving your strobe is all different positions. This is important whether you are shooting macro, fish, or wide-angle. With this 2-arm setup, I'm ready for supermacro, wide-angle or anything in between, so I never have to mess with my arms.
Be wary of arms and clamps from housing manufacturers. I've used many setups with arms and clamps that came with their housing - these are often high-end compact camera setups. I couldn't believe how difficult it was to move the strobe around underwater - no wonder why my friends weren't varying their strobe positions!
