I just purchased an SD870 to use for kite aerial photography. It's desireable to have a fast shutter speed of at least 1/500th, preferably 1/1000th to prevent motion blur when the camera's airborne. I just tried a test shot of a bright but shadowy early morning subject and saw that the camera would chose 1/320th f/8.0 for the exposure.
I loaded Allbest Build 51 and set an overide shutter speed of 1/1000th. The camera still shot the scene at f/8.0, so the photo was underexposed. I tried playing with the neutral density filter setting (ND filter state), trying both the "in", "out", and "off" settings. I get the same exposure no matter what ND filter state I choose.
Unfortunately, the camera doesn't have a Sports mode which favors fast shutter speed. It does have a Kids and Pets mode, but that doesn't seem to affect the shutter speed/ND filter choice much at all.
It would be great if forcing a fast shutter speed with Allbest Chdk would make the camera choose the right ND filter state, or if we could simply force the ND filter state to choose the f/2.8 setting.
One other request: it would be great if there was some way to force the LCD off while running a script to conserve battery power.
Thanks very much!
