Is there something I should be changing on my metering or exposure to get the extra contrast needed to still see the black of the prop?

Not really. When you slow the shutter down, the props are in one position for less time relative to the length of exposure so they get progressively more transparent the longer the shutter is open. Just the way it goes I guess.

Nice full discs. I'd expect better results if there was some sun to put a reflection in the prop.

As Frank says, reflection and sun angle are the key...

See the glare in the windscreen? The prop blades are on just about the same angle relative to me:

Same deal here:

Also, keep in mind that planes usually have props painted black on the back so that same "glint" isn't a distraction to the pilot. In those cases, you need the contrast of the sky to get the prop to register:

You did quite well with snagging full arcs (which aren't the be all and end all if the overall shot isn't sharp) but the Wx isn't doing you any favors.

Thanks guys, I'll try and plan my next trip a little more around the weather and post some results in here.

The black of the props is only covering the background a tiny percentage of the time, so it's not going to blend itself in very strongly.

I can't think of any way of preserving the perfectly smooth disks and getting blacker disks, other than getting less light on the background, and/or more on the props. Then, the contrast of the disks will be closer to the actual contrast of the props.

I absolutely agree with FlyingPhotog. I've found that the best prop blur is all about angle of the sun, and contrast between prop blade color, and background color. As usual, I have the best luck with prop blur near sunrise or sunset, because the sun is down low enough to give you a good angle to shoot across the propeller. This picture was shot at about 7:15am, and the low light really made it easy to get good shots of the prop.

Beautiful Eagle!

What was your camera platform?

I was shooting out of a 150 hp Pacer with the door removed. It was the first time shooting out of that airplane, and it was a nice platform. On the bottom end of the Eagle performance range, but it got the job done.

B-17 Landing (external link) by woodyrr (external link), on Flickr

I need some advice.

I don't get to shoot airplanes very often, but a B-17 was taking people for rides at a local small airport, so I figured that I could possibly get in close to it.

I knew that I had to keep the shutter speed down in order to not freeze the props. This was shot standing on a very windy flight line at the lowest speed I figured I could get away with which was 1/320@ f13 using an EF100-400mm f/4.5-5.6L IS lens at 400mm (640mm APSC equivalent). The aircraft was a long way away and this was the last point during the landing where the background wasn't cluttered with buildings and other distractions. Besides, I liked the angle and the wind sock that appeared in this frame. For me, anyway, panning wouldn't have been an option due to the frightful wind knocking my lens all over the place making in difficult to keep the airplane in shot let alone follow it.

The question is how do those of you who do this all the time take shots with a long lens in the wind while still blurring the props?

Practice...

Set up with a good solid base, try to time shots between gusts and if all else fails, take the lens hood off as it catches a lot of wind.

You got a nice, crisp shot with at least some blur on a blustery day. I'd call it a win and go have a beer!

Thanks. Taking that huge lens hood off might have made a difference.
