"Car in Green". The foreground lighting came from my monolight at 1/16 power. I shot this handheld with a 100mm macro lens at 1/250sec, f/8, ISO 400.
See how I did the background lighting behind the LJ-cut.
I got a sample swatchbook. I'm too cheap to buy sheets of color gels. ;)
They fit nicely on the front of most flash heads! This is my Canon 580ex with a Kelly Green sample. I taped a bit of cardstock at the bottom of the flash lens to hold the gel from the bottom. The lip of the wideangle adapter does a great job of holding it from the top.
While my monolight was lighting the car, this small flash was on the other side of the room, flashing against a white window shade at very low power (I think it was at 1/64)
Here is the same shot from before, except with a blue gel instead.
