Curt Scott has some good photography tips on his CobraCountry.Com website. Basically, you need to do exactly the opposite of what you see on detailing sites. Do not take photos at high noon. Indirect light is better. Never shoot into the sun, always put yourself between car and sun. If possible, shoot during the "golden hour" one hour after sunrise and one hour before sunset. The sun is low on the horizon and the shadows are soft.
Look at the photography in car magazines. Not Muscle Mustangs & Fast Fords, but Road & Track, Motor Trend Classics and Collectible Automobile. Copy what you see.
Work on composition. Put the car in a nice setting, not in your driveway infront of your rusted-out 1953 Chevy pick up. Try to shoot from different positions, NOT JUST STANDING UP. Put the camera at headlight level. Fill the frame with your subject. You're not photographing the house, driveway, old pick up and your car, just the car.
Learn how aperature affects what is in focus. Use a tripod. Above all, you have a digital camera and are not paying for film or development. Take hundreds of photos with different settings on the camera, different angles, composition etc. If you take 100 photos and get 1 or 2 good ones, congratulate yourself.
