Re: long exposure modification -- amp control?
- Hi Ed,
I can't confirm it, but I would assume that it would be similar
to the amp-off mod for the Toucam and Vesta. I did it for my Vesta
Pro, but I have not done it for my Neximage (yet).
If anyone can confirm that the Neximage uses the Sony ICX098 series
CCD, then the transistor across CCD pin 9 amp-off mod would
be the same.
Let us know if you try this,
