Precision photography tools for serious shooters. Calculate ND filters, depth of field, golden hour, star trails, and more - all in one app.
Aperture is the precision photography toolkit designed for serious photographers who want accurate calculations in the field.
Whether you're shooting long exposures at dusk, planning an astrophotography session, or calculating the perfect depth of field for a portrait - Aperture has the tools you need.
CALCULATORS
ND Filter Calculator
Calculate the correct shutter speed when adding ND filters. Enter your base exposure and filter strength, get the perfect long exposure shutter speed instantly.
Depth of Field (DOF) Calculator
Find your exact near and far focus limits. Enter aperture, focal length, and subject distance to see your full depth of field in metric or imperial units.
Hyperfocal Distance
Maximize sharpness across the entire frame. Calculate the hyperfocal distance for any lens and aperture combination to get everything in focus from foreground to infinity.
Equivalent Exposure
Match exposure across different settings. Change ISO, aperture, or shutter speed while keeping the same exposure - perfect for bracketing or switching from tripod to handheld.
Sunny 16 Rule
A quick reference guide for outdoor exposure without a meter. Organized by light condition from full sun to deep shade.
PLANNING
Sun and Moon Data
See precise golden hour, blue hour, nautical dawn, astronomical dawn, sunrise, and sunset times for any date and location. Moon phase, illumination, moonrise, and moonset included.
Golden Hour Countdown
Live countdown to the next golden hour or blue hour from your current location. Never miss the light again.
REFERENCE
Scene Settings Guide
Starting camera settings for 15+ scenes including landscapes, portraits, night, waterfalls, street, macro, and more. A quick-start reference for any shooting situation.
PRO FEATURES
Star Trail / NPF Rule
Calculate the maximum shutter speed to avoid star trailing. Uses the NPF rule for pin-sharp stars based on your camera sensor, focal length, and aperture.
Reciprocity Failure
Essential for film photographers. Calculate the corrected exposure time for long exposures on film, accounting for reciprocity failure for major film stocks.
Crop Factor
Calculate the full-frame equivalent focal length and aperture for any crop sensor camera. Understand your actual field of view and depth of field on any sensor size.
Shoot Planner
Plan your next shoot in advance. Set date, location, notes, and checklist. Organize upcoming shoots and never forget your gear list.
Scout Locations
Save location scouting notes with map pins and photos. Build your personal library of promising spots.
Shoot Log
Document completed shoots with conditions, settings, and notes. Build a photographic record of your work over time.
