August 29, 2008 Desoto Bend Iowa Steam Devils and other Fog Scenes Page 2
|
Hmmm, I just thought of something. I need a boat, or at least a little kayak. Then again, losing my camera gear in a lake doesn't sound too thrilling. I could get some closer steam devil shots from a boat, or just close scenes like the above...etc.

I love these things! Two steam devils attacking that building over there. Or at least it looks that way. I learned one thing with these, and that is just over expose the sunlight on the water. It's hard to give the vortex the exposure it deserves if you don't.

There is actually a really big steam devil at the front of that boat. It looked like they drove right towards the thing when it formed. It was never really defined. It's going up out of the top of the frame though.

This one has a debris bowl! Right above the water.

The motion in these things really is incredible. Looked cooler than the motion in any of the tornadoes I've seen. Just rapid rings appearing to go up and down in there. I will definitely shoot some video next time.

With the right conditions, it is very easy to watch them form over and over. It can at times be hard to get stills of them though. Often you find one right before it vanishes. Staring into the reflecting sunlight doesn't make it any easier. It was around 50-55 now, and the side of my black canon was getting warm. I was using the lens to block the sunlight, holding the camera sideways. The reflected light was just really quite powerful. I actually thought it was warming up rapidly, since it felt so warm now. I then go to a different area later and found it was still quite cool out.

|
I did not spend much time doing these. Maybe 15 minutes I guess. I'll have to spend more time at it the next time around. I'm sure you can get some rather interesting ones.
|
|
Just a hair cool! This one had an outer vortex/sheath around the main one.
|
|
Another shot of the same one. Yeah, I really must get video of these. The motion is simply captivating and interesting.
|
|
In many like the above, that motion is not slow and peaceful. You can tell the motion is quite fast because on all these the definition of the vortex is never really clear. I'm hand holding these, and I believe many where 1/400th or so. Some of the ones up further on the page are close to showing the banding structure in the vortex. Most are blurred, simply because it is changing so damn fast inside them.
