I am flying a UAV equipped with a Canon IXUS 125 HS.
In order to reduce image blur caused by slow exposition time Tv, I am trying to configure the camera with CHDK .
With CHDK, I fix exposure time Tv to 1/500 and use Auto ISo however I get sometimes overexposed pictures with f/2.7 and then some under exposed pictures with f/8.
It seems that this Canon cannot fix the Av...
Does anyone know of a way to fix this?
