Originally posted by savoche Good advice given already. No way around lots of practicing. But I have found that it helps to think of what I do not want to include in my picture more than what I do want to include. That will often force you to change angles, get closer and/or zoom in, all to catch the essence of the subject without including distracting objects.
that is solid advice, especially for a car show, because they are often parked too close together... really need a wider lens.
with the k10d, i settled on 24mm at f/5.6... not too distorted, gets the entire vehicle in focus, and that same angle works well both at the track and at the shows.
