  • Shot Planner: where to stand and when, solved to the arcminute against a 5 m elevation model.
  • Walk & Fly scouting: the site in first person, or from the air around your own tripod.

The photograph, before you take it
Viewfinder

The photograph, before you take it

The viewfinder renders your exact field of view: sensor aspect, focal length, teleconverter, lunar parallax, refraction, horizon flattening. If it looks tight here, it will be tight on the camera.

Shot planner

Stay aligned while time moves

Turn on Hold Alignment and drag the clock. As the sun sinks, Soonlight slides your position along the ground so the sun stays pinned behind your subject, minute after minute.

Walk

Walk around the block

Walk the terrain in first person at eye height, composing with your lens's true frame floating ahead. Hold E on a subject, the sun or the moon to lock on, and the view keeps it centred while you move.

Fly

Scout it in three dimensions

Fly around your own tripod and see exactly what the lens covers, drawn as a gold frustum over the terrain.

Locking

Eyes on target

Hold E on any subject, the sun or the moon, and you lock on: both you and the camera keep it centred while time plays and you move. Watch the rig swivel to follow from the air.

Fly

Direct from the sky

Fly above your scene and place the camera and your subjects from the air. Point where you want them, click, and they drop onto the real terrain below.
