A little more detail on the Goodwood festival of Speed this time.
I look for shots in the rally stage where the cars change direction.
The old rear wheel drive cars will be tail happy here and providing a great shot with flying dust, covering me and the camera in dust as they pass.
Four wheel drive cars may not be so spectacular as they hold the road better, with less wheel spin there's less to show for the speed.
Front wheel drive cars often understeer into the bank, and there may be a shot of them throwing up dust from the front end as they scrabble their way down the bank.
But if it's wet then the cars will be going much slower on the chalk surface - it's like ice and they can't get the drive uphill into most of the corners. They're less spectacular too because wet muddy chalk doesn't fly up as well as dry dusty chalk.
Of course over the jump they're not going as fast, as a landing they could correct in the dry will send the car off into the trees or log piles in the wet. So with classic championship winning cars (and sometimes classic world champions) discretion is advised.
The best light is cloudy, or sun over your shoulder. Sun is unlikely in most spots among the tall fir trees, but on some of the straights at the wrong time of day there is sun on the track. Good illumination, smaller apertures are possible; but dark shadows and glare.
The shot in the sunlight shows the problem with glare, I have to say it's a typical problem on smaller sensors.
I notice purple flare like that much more on compacts, less on micro 4/3.
I don't recall it when shooting with the Canon L lenses and Pro bodies.
Notice the Subaru is moving faster than the Honda, aperture f/10 for the Toyota and f/2.5 for the Subaru, sunlight makes a huge difference!
