The Sabre climbs out after take-off

Sorry about the delay I’ve been away a few days – See my duxford post!
When I mentioned ‘stopping’ I was talking about the propellor looking as if it is stopped if you use too high a shutter speed, not about stopping down the lens.
I usually find 1/320 is about the most I can use and this brings with it the risk of blur due to the combination camera shake and a long lens. I was suprised that slicer got away with 1/640
Does this help?

I think that one of us has got hold of the wrong end of the stick here.
I thought that ND filters were a way of cutting the amount of light entering the camera. I do not see how this affects the distance a propellor moves in a given period of time. Too high a shutter speed results in a ‘stopped’ propellor. I usually use 1/250 or 1/320. Adding an ND filter would mean opening up the lens to a wider aperture, resulting in less depth of focus – the opposite of what I thought was needed.

That was the pose I was hoping to get. You must have been closer to the crowd line than me.
One problem with that pass was that the two a/c hardly ever had the same bank angle probably due to the gusty conditions and it was just about right when you took the shot.
I did wonder if it was the gusty conditions that caused the Hind to ‘bounce’.
Part of the reason for my query is that I was once told by a camera club member that I shouldn’t worry about focussing on a/c because they were all at infinity anyway – something I couldn’t bring myself to accept.
Is it me or is the Demon in the last shot slightly less sharp than the Hind? If it is then I think that the answer to my question is ‘depth of focus’.
Thanks for your reply ( and to everyone else)
