Long-tail route · optics
Use this when image formation should feel physical instead of photographic jargon.
Optics explainer covering image formation, aperture, focal length, lens geometry, aberrations, and sensor behavior with manipulable ray simulations.
At a glance
Live interactive
The maintained version lives at the route linked here, with this garden note keeping the embed and editorial framing.
Best companion
Pair it with [[Color-Spaces]] when you want to move from optical capture into how image data gets represented and transformed.
Time and level
About 15 to 20 minutes. Intermediate. The article is long, but the interaction is easy to enter.
