Free solar pinhole camera simulator for any latitude: preview multi-day sun trails, can aim, and paper framing before you drill.
Frequently asked questions
What is a solargraph or solar pinhole camera?
A solargraph is a long-exposure pinhole camera, often a film can, that records the sun's path across the sky over days or weeks. This simulator shows the trail before you drill the hole or mount the can.
Can I simulate a solargraph in Guyana?
Yes. Defaults include Georgetown and other Guyana coordinates. Near the equator, sun paths are steep year-round; the simulator uses accurate ephemeris for your aim direction and exposure length.
How long should a solargraph exposure be?
Many makers run days to months. Longer exposures thicken the daily arcs and include more seasons. Preview different day counts here before committing paper and a can outdoors.
