Camera tools
Interactive camera optics: thin-lens models of focus, depth of field and blur, and the pinhole model of computer vision.
Thin lens
3D thin lens: focus and depth of field in 3D
The plane of sharp focus, depth of field and field of view of a camera, optionally with view camera movements.
2D thin lens: focus and depth of field, side view
The plane of sharp focus and the depth-of-field wedge in a side view, with lens tilt and the Scheimpflug rule.
Thin lens: defocus blur visualisation
How each point of a scene blurs when out of focus, from the light cone behind the lens to the blurred picture.
Calculators & tables
Depth of field, hyperfocal distance, format equivalents, reciprocity failure and development times.
Pinhole
Pinhole camera: projection
Camera projection as in computer vision: intrinsics, pose, projection matrix and lens distortion.
Pinhole cameras: epipolar geometry
Two cameras on one scene: epipolar planes, lines and epipoles, the essential and fundamental matrices.
