I’m afraid I’m probably not going to be able to support Nikon LiveView in DIYPhotobits.com CameraControl. It isn’t available via PTP or WIA but only via the Nikon SDK which I don’t have access to (and probably couldn’t program even if I could).
However here’s an great thought to get a similiar experience – at least in a studio situation.
Basically use the video out of the camera to to send to another monitor, while at the same time also tethering.
I haven’t tried this — nor I suspect has the person suggesting it — but it sounds like it would be good, presuming you have the two monitors required.
