Ok, I searched with no hits in the photog forum. My question involves how to get good prop arc. For an easy example take a look at this picture. http://img149.exs.cx/my.php?loc=img149&image=mattwn55958331054cn.jpg
For this pic I used a high shutter speed and high aperture, I came out fine but with not with a full prop which is understandable. On the next pic of the same a/c when I slowed the shutter to 1/30 sec. the picture came out like I was looking at the sun, almost completely yellow. How can I fix this? I'd like my prop pics to come out more like this.

Well, the pic you linked to there obviously has too high a shutter speed, so the props seem frozen. Your idea to lower the shutter speed was the correct one. What camera are you using? It seems as though when you dropped the shutter speed, you didn't compensate with a raising of the aperture! If you're going to let more light onto the sensor/film through a longer shutter opening, you had better decrease the amount of light that can hit the sensor at once by raising the f-stop value! Normally the camera should automatically decide on an apropriate f-stop value for the shutter speed you selected, but maybe you had it on completely manual mode?
Hope that helps,
I guess that's what happens in the end, you start thinking about the beginning.

I'll give you an example of one of mine (sorry for self plugging) http://www.airliners.net/open.file?id=794484
This was shot hand held (a good tripod is convenient)
Exp 1/60, F14 (set by the camera) ISO 100.
Very carefully follow the object (if it is moving) and hold the camera very steady. If there is too much light consider exposure compensation or even a neutral density filter.
And most important, keep practicing.

When it's bright and sunny, it's tough to get a long enough exposure to get a full prop rotation. This required 1/30th at f25, which is as far as the lens would go. If it were any brighter I'd have been stuck.

Thanks for all the help guys! I am worried that with my current camera, an Olympus C-765, I might not be able to get a high enough f-number. I think my lens only goes up to f/8 or f/9, and you guys are talking about f/14 and f/22. I guess I will have to practice some more, hopefully it works out. Thanks again.
