 Define Object Size: Select this option and click the
button to pause the live view.
Use the mouse to outline a region matching the normal size of the targeted object. Click the
button to resume.
 Define Image Depth: When the object moves toward or away from the camera along a path,
for example, a hallway, it appears larger when it is closer to the camera and vice versa.
Rather than using a fixed object size, you can define a maximum and minimum object size
according to the object’s proximity to the camera.
