If you're moving the camera around with a null as a parent then without moving the CTI (current time indicator) remove the parenting. Make note of the camera position and then reattach the parent.
I'm not exactly sure what you're trying to do but that's how to figure out where the camera is without writing a complicated expression.
Well, I'm trying to link the camera in Psunami to the Comp camera, basically writing expressions for rotation and position so that when the comp camera moves, the Psunami camera will match-move... BUT if my comp camera is parented to a Null object, the expressions that I put on the camera's rotation/position don't work (at the link I put in my original post) because there are no values in there.... I was hoping to find either A) revised expressions to put on the Null object's Rotation/Position, OR B) somehow force after effects to reveal the Camera's Rotation/Position values even when it's parented to a Null...
Thanks again for any help
You have to use layer space transformations and then alculate the difference between the psunami camera. If I remember correctly it is not the same as AE's camera.
Make a new null, and add an expression to the position property.
camera = thisComp.layer("Camera 1");
This will "parent and bind" your new null to the camera, and also if you check the position properties of the null, this spits out the "actual" values.
(Won't solve all the Psunami issues, as stated above the layer space transforms are in a different order, but this solves your original question.)
