I just tried a new approach that seems to work ok. Here is a sample test script:
TAKEPIC,EMERGENCY,-,00:00:00.0,5DMKII,1/1000,8.0,100,0.000,RAW,,N,Corona bracketing 1000
TAKEPIC,LAST,+,00:00:01.1,5DMKII,B1 .000,8.0,100,0.000,RAW,,N,Corona bracketing 1000
TAKEPIC,LAST,+,00:00:02.5,5DMKII,1/500,8.0,100,0.000,RAW,,N,Corona bracketing 500
TAKEPIC,LAST,+,00:00:01.1,5DMKII,B1 .000,8.0,100,0.000,RAW,,N,Corona bracketing 500
TAKEPIC,LAST,+,00:00:03.0,5DMKII,1/250,8.0,100,0.000,RAW,,N,Corona bracketing 250
TAKEPIC,LAST,+,00:00:01.1,5DMKII,B1 .000,8.0,100,0.000,RAW,,N,Corona bracketing 250
TAKEPIC,LAST,+,00:00:03.0,5DMKII,1/125,8.0,100,0.000,RAW,,N,Corona bracketing 125
TAKEPIC,LAST,+,00:00:01.1,5DMKII,B1 .000,8.0,100,0.000,RAW,,N,Corona bracketing 125
In 15 seconds it takes 6x1000, 6x500, 6x250, 6x125, total 24 images.
The camera is set to continuous shooting, and I only have a USB cable.
The first TAKEPIC sets the exposure, the second one is a BULB exposure, so the camera goes into continuous shooting mode for one second and takes about 5 images per second.
It's important to have a good size delay to allow the CF card to catch up before the next image with a different exposure is taken.
My camera/card combination can take about 3 RAW images per second.
Before my script was limited by the 1 second delay to program the camera exposure. Now it's mostly limited by the CF card speed.
Does this make sense?
