Slaving speedlights optically in bright sunlight is a challenge. You will have less working distance than you would have indoors. It can be done if you can work with limited distances between the lights. The relatively wimpy output from the D300 built-in flash will make this even harder.
First, you need to allow the D300 to communicate to the SB-800. Use Channel 1, Group A, for example. Again, consult your manual.
I\'m guessing you want to overpower daylight to some extent by underexposing ambient by up to a stop and then add some fill to balance the car exposure with the speedlight. If this isn\'t correct, let us know.
Problem #1: You get more fill power from the flash as shorter distance, with higher ISO, and with wider apertures. The catch; however, is that in bright sun your shutter speed is going to peg way past 1/250, which exceeds the sync speed of the flash. This then requires setting the camera to high-speed sync (FP mode) in the menu so that you can use the flash at high shutter speeds. But the flash has less effective power in FP mode. You might need to put a ND filter on your lens.
Personally, I would set the camera to manual exposure and then dial-in the aperture and shutter speed you want to get the ambient exposure that works for you. Then take a shot, chimp, look at the flash exposure, and then adjust the flash output until you get the balanced fill that you need.
I think you\'re going to need a more powerful light or more speedlights.
The gadgets hanging below the speedlights don\'t look like Pocket Wizards or Skyports. They could be power packs.
