I use ISO to bump up aperture. set to a shutter speed depending on speed and focal length (the faster you have to pan the faster the shutter speed you use unless your ace).

Don't worry about ISO, just set at 100 and forget it.

Unless its very dark or you need lots of shutter speed you don't need to go higher.

At ISO 100, pick shutter priority mode and a shutter speed that will cater for your effect. If you want blurred wheels go for slower than 1/100th anywhere down to 1/15th ish depending how brave you are that you can track the car for 1/15th of a second and not blur the car as well as the background.

Longer focal lengths it becomes harder to pan anyway so if its critical speed up to 50th-80th for safety shots that will probably come out OK.

Experimentation will help but don't expect consistency, you might get sharp cars at 1/15th and blurred ones at 1/100th, just depends how steady your hand is on that shot, amount of wheel blur depends on car speed etc. etc., many factors.

This should work OK, the only time it will not is if there's no enough light even for slow shutter like that, and your aperture indicator will normally flash to tell you thats what you have but its not wide enough, ONLY THEN up the ISO and you'll get more sensitivity in low light. Higher ISO adds grain and should only be used if you anticipate or experience problems. Otherwise ISO 100!

"the red car and the blue car had a race...
the der der dumm dee dumm stuff his face..." :o

read the guide at the top mofu

I was panning like a prospector in the middle of a gold rush. :o

i think u have to pan with the camera

What shutter speed (or general settings for that matter) would be recommended. Obviously ISO 400 would make the car appear to be standing still, but even using 100 or 200 I was only gettin a slight blur on wheels:



That was when they were at full pelt down the straight, were they just not goin fast enough or was I too far away etc? :look:
