A busy day on Friday - in fact one of my busiest days for a few years. Here
is a few from the morning session, the rest I'll post later. Hope you
enjoy viewing them as much as I did taking them.

ps ~ notice I bagged that Navy hawk after all !!

Love it!!
We got to see some of the countryside in these photos and you sure do have a good location pegged out.
The Herky photos are spectacular. I really enjoy seeing the spinning propellers instead of frozen ones. What's the secret to getting blurred propellers and a sharp aircraft? Someone told me it had to do with the shutter speed being 1/100 for each hundred millimeters of lens used. In other words, a 300mm lens requires 3/100 exposure at whatever f stop the camera decides to throw in. Others say there is an f-stop for two bladed props, one for three bladed, etc. Will you share some techniques with us? Tom in Pensacola

Well first its no secret, if you download my pictures and right click on a
file to select properties you can read the EXIF data to see what settings I
used.
I find that the slower the shutter speed the better to show spinning props
but this has to be balanced with my ability to pan with a big lens at the
same speed as the aircraft passes. I usually use 1/160th sec but some of
these were taken at 1/200th sec. With static or aircraft heading straight
towards me the image stabiliser on the lens can be used to great effect.
It makes no difference what size lens you use - its the time that the
spinning props are exposed to the 'film' or sensor. As for techniques I can
only point you to practice and more practice. I do not use a monopod or
camera strap, I just try to pan smoothly. And a digital camera enables me
to take many shots and risk loosing a few (or a lot).
