I think most of those beach shots were done between 8 and 20 seconds and between f/8 and f/11 or so. Just guessing. Using the lens mentioned at the bottom of the post, a Tamron 17-50mm f/2.8.
These are unofficial wedding photos taken with my camera that was handed between two people. Melody's sister did the actual photos and they're posted on another website.
With her two daughters (now my stepdaughters)
With her parents
With my parents
The wedding was done on the bridge behind us in the first photo (Faust Street Bridge in New Braunfels, TX) at 11am. We were already starting to sweat, even in the shade. It's Texas! The reception was in walking distance and air conditioned. The back yard was used for family pics and such.
