Does TPE use True north or Magnetic North

All versions of TPE (The Photographer's Ephemeris) show azimuths and bearings relative to true north.

Our iOS app has a setting to use Magnetic North instead. This is rarely required unless you are using a field compass which has not been offset for local magnetic declination. If you're uncertain, or you're not using a field compass, we recommend leaving this setting off.

Note: enabling magnetic north has no effect on how the azimuth lines are drawn on the map. Changing a setting doesn't change where the sun will rise ;)
