If you're after a fairly realistic looking you might want to try something different.

What I do is:

1. make a selection around the prop. (the four blades but not the spinner or hub).
2. copy the selection and place if on a new layer.
3. make selection around hub... copy it and place it on a new layer.
4. layers should be hub on top, copied prop middle, photo bottom.
3. on the original photo layer... use the stamp remove the original prop as inconspicuously as possible.
4. make a circular selection around the prop on the prop layer. (you can use the transform selection tool to fit the elipse shape perfectly to the tips of the prop)
5. use the radial blur tool to blur the prop... try varying degrees of blur to get what you like.
6. export as j-peg.

This approach seems to work pretty well because it uses that actual prop instead of painted pixels.

Now if you could just figure out a way to make those props "Wind Generators" you could get Federal "GREEN" grant money for it! :wink:

Nice Holedigger!

Wouldn't it be cool to take 2 of the engines on one side and rig them up so they spin up? Isn't there a B-25 somewhere that does that? IIRC though it was turning super slow.

I think the B-25 at the Nimitz/Pacific War Museum in Fredricksburg, TX does that prop spin thing

Django...I had talked to the fella in charge of taking care of the girls there at Grissom (Richard) about that very thing...building some sort of support inside the nacelles and hanging a prop on a shaft that would turn with the wind as it is always windy there. He told me that idea was floated, but was soon dispelled as there was no way to keep the unwashed masses from walking into one of the propellers as it was turning. Ya see, all of the girls there at Grissom are surrounded by only a very short yellow rope. It is posted in several places to keep behind the ropes, but as I am sure you are aware, some folks just can't help themselves from wanting to touch, scratch and tap on the sides of a plane. One example that comes to mind while I was working the grounds there one day was when I saw an older gentleman (?) with two young children walking around behind the KC-97 where we have an F-84 sort of rigged-up in an aerial refueling scenario. I swear to God that the two little children had climbed up, one on each wing of the F-84 and were jumping up and down...much to the glee of the older gentleman (?)! When I told the gentleman (?) to get those kids off of there and get out of the park, he said that he paid taxes and had every right to be there! When I made him aware that the aircraft were still owned by the US Air Force and the penalties for destruction of government property were pretty severe, he hastily got the Hellen out. Yes! I did maintain my composure and did not react with my first gut feeling of grabbing my .357 out of my car and doing a bit of varmint hunting :twisted:

So...that and so many other things I saw there and at museums and airshows is exactly what Richard told me about why we could not free-up any props and let them turn in the wind...the unwashed masses would walk into one, get hurt and sue the bejeezers out of the museum.

I think sharping the leading edge of the prop might take care of that and give the vultures something to eat.

too bad.., sounds like Darwinism at it's best! "Natural selection" as the maroons are culled from the herd as they ignore the signs and cross over a rope and into a spinning prop!

we should put up spinning props all over the place!!

I was thinking once it gets moved inside and you can control how close people can get. It's going to be set up with some kind of visitor barrier most likely. I don't know what kind of shape those engines are in, but maybe the museum could come up with some junk motors to modifiy with some kind of electric motor set up to turn 1000 rpm at the top of every hour for 5 minutes. Have a recording of one starting up and then running, with the sound cranked up.

I'm not an engineer, so I have no idea how to do it, but it would certainly be unique and maybe put a smile even on the faces of the folks who think they should be flying anyway.

...or just turn over slowly several times, popping and banging and fill the place with smoke! That would be fun too! ;-)

Have to have a grease smeared CC standing there with a big hammer waiting to adjust it!

My suggestion... works everytime.... shoot it slow.... on the border of handhold shake.... don't fake it... just shoot it right.

my two cents, YMMV,
