Tethered shooting Mac

Free Mac software for tethered shooting.

Sofortbild - Mac Tethered Shooting

But not for all models. I looked at this for the D3100 but the lack of available APIs means that model has severe third party limits.

It works with my D7000 but not the D3000. I plan on playing with it more, when I get the chance.

Will this software see/control a camera with the Nikon Wifi WU-1b connector???

edited to add... Nope... Doesn't see the WU-1b...
