# Camera Calibration Settings

## Calibration

In the Calibration tab, the user can revise the Camera’s calibration values, such as sensor size (in mm), pixel size (in px), as well as camera position and camera orientation. These options should not be altered unless necessary, and only then should be used in very special cases. Use [CameraSnap](/spatialexplorer-8-and-9/user-interface/toolbars/workflow/camera-snap.md) to modify these values:
