Heres some of the pics that I have been fooling around with for a while.Most are drift pics and all are single car pics, no full races yet, but they are on the way!
Tips: Make the shots bigger, if your going to have a preview then a small pic is better for previews. Also shots 3,4 and 7 need to be made more brighter.
Oh and remember to check the "remove the resolution bar" option, it looks neater. And dont resize the image if you are using thumbnails. It will come to you gradually, just need some experience. Good start!
