Anyway, some results. I did not have Lightroom/Photoshop, so this is pure K10D JPEG in-camera processing (not my normal way of processing images :P). I made these just to show off the lighting possibilities of a single strobe, off-camera. I did not use a light-stand, just put my strobe on a super clamp.
The cars are on a round piece of glass, again on top of large A1 size sheets of paper.
Look at how the umbrella reflects in the front of the car.. Strange specular highlights anyone?
