Sure, in professional car shoots they use additional lights for that but I don't think it's a must have.
First of give us the EXIF info of this shot. What's the shutter speed, aperture, ISO, focal length?
This shot of course is way too noisy. I wouldn't have a problem shooting this with ISO 100 at f5.6-f9 with longer shutter speeds just to avoid the noise.
Your friend either has to hold still for as long as necessary if he wants to be identifiable but personally I like an element in the frame that is blurry especially in long time exposures. So he could be actually walking around the car which could create some nice effect.
Also if you wait longer until the sun is even further down, just do a 20 second exposure having him walk around the car with a flashlight. That would give you some funky streaks.
creisinger - This is a 6 shot exposure. All of them were at ISO 1000, f/22. Shutter speed varied from 1/8 - 4sec. Shot using D300s at 19mm (using 18-55mm)
Personally I liked the noise and the vignette, but here's another version without either:
Those are some nice ideas creisinger, I'll try that out when I get a chance again!
I mean, was it your intention to go up to ISO 1000 to get the noise?
Noise/artifacting is usually not desired when shooting. If you want to add grain later that's a different thing but your first shoot looks kind of "off" to me just because of the noise.
You're right f/22 is probably too less. I wanted the grains on the road, the car and the mountains to be in focus. So I tried it out with f/22. I guess f/8 could have achieved the same thing?
I think the aspect ratio can be improved. You may not like this one but I think the native format is not ideal for this shot either.
I just pushed the colors and a bit of contrast. Not much more I would do though as I have to take into consideration the original image.
It was only a 2 minute edit anyway.
I also rotated it a couple degrees counter clock wise and oh next time: make sure to either point the front tires straight ahead or at a 30+ degree angle.
