Camera framing

Focal length + sensor size + subject distance → field of view + framing reach.

For placing PTZ cameras in conference rooms, lecture halls, and live event spaces. Pick your sensor (1/3" for most conference cams, full-frame for cinema rigs), enter focal length and subject distance, get back the horizontal field of view, the width it actually frames, and the distance you'd need to be for common framings.
