I'm pretty new to photography and I've been doing a little practice with scenery. Now my new goals are automotive photography and portraits. My first take is shooting a car thats an alpine white color (Not bright white but not cream) Its a fairly new car 2003 and its a BMW. What are your suggestions for background on where to do it. What time during the day? Any suggestions would be appreciated. BTW I'm armed with a Nikon D80 with a 50mmf/1.8. Any lens suggestions for car and portraits?
