Soonlight

plan the light before it happens

Plan the 12 August 2026 total eclipse shot down to the arcminute. Soonlight rebuilds the site in real terrain and real optics: a geometric twin of the moment, years early.

  • Lens-accurate viewfinder: your exact sensor and focal length on true sun and moon discs, terrain silhouettes out to the horizon.
  • Shot Planner: where to stand and when, solved 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

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

Where to stand, solved

Pick a goal like “the sun touches the treetop” and the map draws the wedge of ground it works from, checked against terrain. Hover the wedge and you stand there for real, live in every view.

The whole day on one strip

Sun and moon altitude curves, contact times C1–C4, rise and set, playback up to 1800×. Scrub the eclipse like a video you already own.

Fly mode: camera on tripod with the gold lens frustum
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.

Walk mode: the true-lens picture frame at eye height
Walk

Compose at eye height

Walk the hillside in first person. The gold frame ahead is your lens's exact framing, live while you move; when the composition clicks, you are standing on the spot.
