Camera Companion

Camera Companion is the go-to reference and calculation app for photographers at every level — from beginners learning the exposure triangle to experienced shooters planning a macro focus stack or astrophotography session.

11 PHOTOGRAPHY CALCULATORS

• Depth of Field — Calculate near/far focus limits and total DoF for different sensor sizes and focal lengths.
• Hyperfocal Distance — Find the optimal focus distance to maximise sharpness from foreground to infinity.
• Field of View — Compute horizontal, vertical, and diagonal angles of view plus physical coverage at any distance.
• Exposure Triangle — Solve for aperture, shutter speed, or ISO; explore equivalent exposures across the full stop range.
• ND Filter — Calculate the new shutter speed after adding a filter, or find the filter strength needed for a long-exposure target.
• Star Rule — Apply the 500, 400, or 300 rule, or the precise NPF rule, to avoid star trails in astrophotography.
• Safe Shutter — Find the minimum safe handheld speed with or without IBIS/OIS stabilisation.
• Flash Calculator — Solve guide number, distance, and aperture relationships for any ISO.
• Focus Stacking — Determine step size, frame count, and total travel distance for macro and close-up stacking.
• Time-lapse — Calculate frame count, clip length, storage requirements, and estimated battery use.
• Crop Equivalent — Match field of view and depth of field across Full Frame, APS-C, Micro Four Thirds, and Medium Format systems.

30 REFERENCE CARDS

Reference cards give you the essential settings and practical tips for any shooting situation, organised in three sections:

Basics (8 cards): Exposure Triangle, Aperture & Depth of Field, Shutter Speed, ISO, Stops, White Balance, Histogram, Bracketing.

Techniques (6 cards): Long Exposure, Bokeh, Panning, Sharper Photos, Flash Technique, Light Painting.

Genres (16 cards): Landscape, Stars & Astrophotography, Night Photography, Fireworks, Macro, Architecture, Product, Storm & Lightning, Fog & Mist, Beach, Sports, and more.

Every card includes recommended settings, practical tips, important warnings, and direct links to the relevant calculators — so you can go straight from reference to calculation without leaving the card.

GLOSSARY

An in-app glossary covers 18 essential photography terms — from Aperture and Bokeh to Stops and White Balance — with clear, practical explanations for every level.
