Thanks, bill. I tried, over and over, to get propeller blur but I couldn't get the right setting. The camera is just too fast and it stopped the props every time! LOL Now if I wanted it to do that...it wouldn't.
the difficulty getting the props to blur has to do with your shutter speed - it must be close to the rotational speed of the props (?So how do I figure the that out??)
I have used trial and error - but every place I go to shoot airshows the crowd is kept pretty far back from the runways and they will only fly overhead if they are above a certain altitude (it's apparently ok to crash into the houses a mile away - but not into the crowd viewing - don't think it's just about #'s of potential injured and dead - more about pr..:-))) making it necessary to used a longer focal length. Since I have a hand tremor I can't ever (well almost) shoot hand held slower than the inverse of the focal length so I would need a tripod to shoot at a slow enough speed to capture the blur.
Wow - that was a long-winded response, wasn't it? LOL
bill, did you see the one I got of the blurred prop? I did do it and I only did it by slowing down the shutter speed and taking a couple of shots then repeating. It ended up blurring the best at 1/20. That apparently was as low as I went. I'll have to go back and try at an even slower speed but I'll be needing the tri-pod as I started to get blur at 1/20 freehand.
