How about reading ADC channels (GetAdChValue())? This voltage can be connected to ADC.

I remember on CCD webcams, if you reduced the voltage a bit, the image brightness was slightly darker.
Thanks Leonardo, thanks ewavr (no, it is not connected to ADC). Couldn't produce anything useful, sorry. At least now I know there are twelve ADC channels measuring who-knows-what...

I think this is in the trunk already, rev. 728.

I was initially excited to see the exposure limit broken but the results i see are of low quality. why is that? yet many people are still excited about the results. how are they taking advantage of the feature? is there any reason to believe that results would be particularly better with another camera model? my a650 gives quite nice images at 65s

quietschi i guess we can also check your patch in, i mean, if you found the adresses in a legitimate way and did not just "guess" them ;)
As there's no feedback about other platformsubs, i cannot tell if it's working for 100c and 101b.
102a is working for me

awrite, just checked in s5is, a570 & ixus70 in #750.

Hello,

i've tried on my A590is the new a590-101b-0.9.8-750-full.zip.
The extra long exposure dosn't work on this camera. It stops after 64 secondes.

Greetings

Pit

thats because the a590 is not included in the extra long exposure club yet.
