Ok—I’m shooting a ’68 Camaro this past weekend, and I’ve just got to have a shot of this thing’s rear suspension. In this case, however, the car was just a bit too low to get down there with a normal camera-on-tripod setup. There are devices made for shooting at such low angles, none of which I happened to have with me at the time—and there were no lifts handy, either. So, what to do? There are probably several other ways I could have Rube Goldberg-ed it, but that's the thing about improvisation--it just happens how it happens. So, once sprawled on the ground, the camera’s lens ended up balanced on a tripod leg, while the body was steadied by the nearest thing at hand—a rock. Looking back at it now, there are items in my camera bag that could have substituted for that parking lot rock. But since I already had my face pressed into the pavement to line the shot up, it just seemed natural to grab that rock and put it to use. Sounds a bit caveman-ish, doesn't it? It sort of felt that way, too. But it worked.
