What's New in GeoLog
3.3
August 14, 2026
This update improves Partial and Annular Solar Eclipse accuracy in Ephemeris, adds Barrel EV values for older cameras, and adds links to SunQuest for shadow planning. Smarter Eclipse Detection Solar eclipse detection is significantly more accurate, and now tells you whether an eclipse is Partial, Annular, or Total — not just that one is happening. More Accurate Moon Phases Fixed the moon phase countdown so it always counts to the nearest occurrence of a phase, instead of occasionally showing a confusing number of days. Barrel EV in the Light Meter The exposure light meter now shows a third reading — Barrel EV — the number a vintage EV-coupled lens or shutter (like a Hasselblad CF or Compur) would show for your current aperture and shutter speed. A quick way to cross-check GeoLog against a physical camera. SunQuest Integration GPS Options in Location Detail and Ephemeris now link directly to SunQuest's Building Shadows and Building & Terrain Shadows views — already centered on your location, heading, and time — so you can see how shadows will fall on your subject throughout the day and year. SunQuest is a separate app, available on the App Store. Smarter links to TPE Opening The Photographer's Ephemeris from GeoLog now includes — dates and time added to match the date being used in Ephemeris. You can also tell GeoLog how far away your subject is, from across the street to a distant mountain, and it'll drop TPE's secondary gray pin (geodetics) at exactly that spot and zoom the map to fit both pins perfectly. Ephemeris Quick Links A new button in Ephemeris jumps straight to SunQuest or The Photographer's Ephemeris using the exact date, time, and heading you're currently viewing, for even more location research. Both are separate apps, available on the App Store. Thanks for using GeoLog!
