The midsummer Sun rising under high cloud over Salisbury Plain, 2500 BC, rendered from the solved light

For productions

The precise light of any place on Earth, at any moment in history.

You build the set. We give you the natural world around it — the sky, the light and the land, exactly as they were.

Asked often

Quick answers.

Does it work with our renderer?

Yes — Unreal, Houdini, Maya, Blender or Nuke, set up with a short install. Your look stays yours.

Our renderer already has a sun.

It places a sun. This adds the year, the stars, the colour and strength of the light, the true softness of the shadows and the real skyline.

Is this AI?

No. Every value is solved from physics and published data, and names its source.

What do you need from us?

Places, dates and times. Nothing about the story; nothing kept after the job.

How fast?

Within hours; emergency delivery when a shoot can't wait. The land of another era takes longer, agreed with you.

Our script changed the date.

We re-solve it and send the new version, the old one kept.

We use HDRI sky libraries.

A library sky is from another day and another place. This is the sky over your place, on your date.

How is it licensed?

Per production, by its size and the number of scenes. By enquiry.
