Photography Calculators — Creative
Optics and exposure planning: crop factor, exposure triangle, hyperfocal and depth of field, flash guide numbers, panorama coverage, star trails, and golden hour timing. Depth of field depends on sensor size, so set crop factor before trusting a distance figure.
All Photography Calculators
Calculate equivalent focal length and field of view from sensor crop factor.
Calculate correct exposure settings balancing aperture, shutter speed, and ISO.
