I'm using A1400 for short kap session with a simple script similar to intervallometer.
Camera is in P mode and when the scene becomes very bright the ND filter comes in, reducing the shutter speed significantly.
I've tried to use the following command
but the ND filter is still active.
also put it "out" in the chdk menu but still active.
last I've tried the kap and uav script with 1/800 as minimum speed. It works for the min speed but, I would have anticipated to have overexposed pics with strong ligth and actually the ND filter comes in, despite setting the correct "out" position in the script menu.
Any idea to avoid this ?
