This brief clip is of the final portion of Bob Grimstead's 2008 acro display in the Fournier RF4 at the Perth Red Bull Air Race.

Several things went wrong and I lost the initial part of the display due to the rig twisting on the tripod head and losing harmonisation with the sighting camera when I pointed to high overhead.

It was purely my own stupidity because I forgot to put in a second baseplate lock stud.

There was also an incusion into my walkspace around the tripod by a professionally equipped but late arriving member of the public who was very pushy and upset a few who had pegged their spot from about 6-00am that morning.

By the time the display occurred, my attitude was all wrong and my workmanship suffered.

The ground-to-air vision was shot with a Mini35-400 on front of a Sony HVR-Z1P with a Nikon f2 200mm with Sigma doubler on back of it.

Aperture on the 200mm was tightened to f4 to try for deeper depth-of-field which put it with the doubler in the region of artifacting for groundglass work.

This prime lens plus doubler works better than the Sigma zoom but a harmonised sighting camera is now not an option but a necessity. At an effective 400mm, there is likely no advantage by going the groundglass route over using an optical doubler direct-to-camera but I am making do with the hardware I have.

The crowd vision was shot with the same Mini35-400 on a Sony PMW-EX1 with the Sigma f4 - f6.3 50mm - 500mm zoom on the previous day.

Other than conversion, no other enhancements have been done.

Bob's own SD tail cam footage from Saturday can be seen on that other site at the following web addess.
