Live gives you the option to fine tune the camera position of a finished solution using the tools on the Fine Tune control panel.
The Nudge Tools provide a manual method for making minor adjustments to camera position on selected frames. The adjustments you make to a solution using the Nudge Tools are automatically saved with the solution. Do not re-solve, because the solver would overwrite your adjustments.
To adjust the camera using the Nudge Tools
Track - Move the camera up, down, right, or left.
Dolly - Move the camera toward or away from image plate.
The camera moves one increment each time you press the arrow key.
