"Good sharp digital images you can cropped for extreme close ups.  Don't forget to create a B&W version of the image; it might look better in B&W.  Sometimes dull colors turn out great in a B&W format and you'll be able to salvage the image.  A panorama style image might be good for views of motorcycles lined up at the start gate or in-line skaters going around a turn or as an image of the entire stadium.  A little increase in saturation always brings out dull colors but do not over-saturate."
