I was browsing through some photos when I found a handful with prop vortices. I was wondering how to get this effect in pictures or if it is an isolated occurance, maybe perhaps controlled by atmospheric conditions such as temp/humidity. Thanks for any help!

My experience is that it often occurs on rainy days. Light rain in the air, and most props I've seen taking off get them nice vortices. Unfortunatly, I have never managed to get a proper shot of that happening yet.
Just returned from my UK holiday btw, MAN was great.

You do have a better chance of witnessing this phenomenon when the dewpoint is higher, not so much the humidity. In that, if someone could offer some sort of insight on how the hell my C-2 Greyhound photo has that much condensation at North Island, I am all ears. It damn sure wasn't sticky.

I think prop "vortices" are the same effect as those condensation trails you sometimes see from flaps or wingtips etc. If I remember right (in most cases I don't), the temperature and dewpoint should be close to each other for this visible condensation to form.
