I am trying to configure my Canon IXUS 125 HS with CHDK so that I do not get image blur caused by slow exposition time Tv.
I fix wuth CHDK exposure time Tv to 1/500 and use Auto ISo however I get sometimes overexposed pictures with f/2.7 and thn some uinder exposed pictures with f/8.
It seems that this Canon cannot fix the Av…
Does anyone know of a way to fix this?
Try a higher shutter speed for starters what sort of platform are you flying it with?? Is the lens out of the wing that often helps.
I am flying with an eBee…
i did also try to use Tv override 1/1000 with CHDK but I get the same problem some photos are taken at f/2.7 with good results but then somehow others are taken at f/8 with Tv 1/1000 and then I get underexposed photos…
The aperture will just not stay fixed at correct value which would be f/2.7…for tv 1/1000 and ligh conditions…
I did do also try with fixing Tv to 1/1000 and still I get sometimes good exposure with Av f/2.7 and then Av changes to f/8 and I get under exposed images…
