Camera is ELPH300(IXUS 220HS) with 1.2.0-3418 CHDK.
Personally, I only use the 1.3.0 version of CHDK. Despite the name, it has always been very stable for me. And it does a much better job of focusing at infinity on a lot more cameras that 1.2.0
1. What metering mode we should use in genarally? Does is make any difference for exposure or will chdk/KAP&UAV overdrive this setting anyway?
The script uses whatever metering mode is set in the camera. It does not try to override it.
2. Not sure about what is possible with usb remote. Is it possible to do following at one flight:
a. turn camera and script running on/off?
b. Zoom in/out?
c. Change camera mode between video and script mode? Recording video on/off?
I can use Arduino to generate pulses, but not sure what are actually the limits and is possible.
The latest version of the script has "place holders" where you can insert whatever code you want to run for any particular pulse width. Changing zoom position, starting and stopping video is all possible. Turning the camera off is possible as is stopping the script. But turning the camera on or starting the script is not possible.
@param e Exposure Comp (stops)
@default e 6
@values e -2.0 -1.66 -1.33 -1.0 -0.66 0.33 0.0 0.33 0.66 1.00 1.33 1.66 2.00 <--missing "-" for negative 0.33??
Thanks - I'll fix that in the next update. As it stand, selecting the first 0.33 value will give you -1/3 stop ev comp, selecting the second 0.33 value gives you +1/3 stop ev comp. It's just the label that's wrong.
2. When using Video Interleave and Video Duration the camera stops responding after hitting Interrupt button, when camera is taking video. Have to take battery out to reset. Interrupt works if it is done during photo shoot.
I'll look at that but it may not be something that I can fix.
