Thanks! It was hand-held, which, as you say, isn't very hard with a wide lens. In general, of course, the slower you go the less the chances of success, but at least some should work and you can go for the percentages. With practice, you can increase your success rate at slower speeds.
I guess I'm a semi-pro. I've sold some stuff and have had shots in a few magazines, though not nearly as much as I'd like. It's a difficult genre to profit at.
How cool, I love car racing but have never tried takind pic of any cars in action. You can really feel the speed in this one. 1/30 sounds slow, did you have a tripod and pan or were you hand held? I suppose with a wide angle you sort of can hand hold it! But you must have been really close, are you a pro?
Thank you! If I recall, it was probably something in the range of 1/30, so the aperture would have been f/16 or so. It's at the end of a fairly straight and they're braking very hard at that point.
