I'm sure you've probably seen one or more photos online that fall into the class of "Levitation Photography." After my wife brought home a teeter-totter for the kids to play with I felt inspired to try my hand at one.
This shot took about an hour to photograph, and another two hours to process. Some things went wrong during the shooting portion that caused the post-processing work to take even longer than I'd anticipated, but altogether I'd say it came out pretty good.
Now I have a couple of more ideas in this theme that I want to pursue when I have time.
