        "description": "Camera and optics maths as an API. The depth-of-field endpoint computes the near and far limits of sharp focus, the total depth of field and the hyperfocal distance from a focal length, aperture and focus distance, using the circle of confusion for your sensor format (full-frame, APS-C, Micro Four Thirds, 1-inch, medium format and more — or your own). The field-of-view endpoint gives the horizontal, vertical and diagonal angle of view for a focal length on a given sensor, plus the crop factor and the 35 mm-equivalent focal length. The exposure endpoint computes the exposure value (EV) from aperture, shutter speed and ISO, and can also solve for the shutter or aperture that hits a target EV. Everything is computed locally and deterministically, so it is instant and private. Ideal for photography and videography apps, camera and lens tools, focus-stacking and landscape planning, and teaching exposure. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. This computes camera optics; for reading EXIF metadata from photos use an EXIF API."
