Long Exposure Toolkit2.6 - App Store

Beautiful light doesn’t happen by accident. Long Exposure Toolkit gives creative photographers the tools to plan the light, find the moon and stars, calculate long exposures, and get the shot right - from golden hour to deep into the night.

PLAN THE LIGHT, NOT JUST THE SHOT
Track every phase of natural light throughout the day, including civil and nautical dawn, blue hour, golden hour, solar noon, sunset and dusk. Follow the live sun-path arc, see exact times for every transition, and get a live countdown to your next photographic window.

MOON, STARS, AND THE NIGHT SKY
Point your iPhone at the sky and the Moon Finder guides you towards the moon using the live camera and a precision compass rose. Follow the moon’s path through the night, check moonrise and moonset for your location, and plan for upcoming lunar eclipses.

For star-trail photography, choose any star or constellation from the built-in catalogue and view its declination arc - ideal for planning and compositing very long star-trail exposures.

LONG EXPOSURES, MADE PRECISE
Use the built-in light meter to measure the scene, select your ND filter strength, and quickly calculate the corrected shutter speed. When exposures run into minutes or hours, the built-in timer counts them for you and chimes when they’re complete.
