WOW! You've got some great shots there. What kind of camera are you using? If you are using a DSLR, which one and with what lens with f-stop? Really nice portrait style family shots! Thanks for sharing.
I use a Canon G9 in an Ikelite housing with a DS125 strobe. I do most, but not all of my shots @ ISO 80, shutter speed @ 1/100 sec and aperture on auto. The strobe is usually set on auto also. My wife does the touch up and or cropping with Picasa because it's quick and easy. Thanks, and you're welcome.
