TPE 0.7.5 released

The Photographer’s Ephemeris is now at Beta version 0.7.5, a few days later than planned, but finally done.

The new version doesn’t look radically different to the last, but has a few nice enhancements under the hood.

Primary amongst those is automatic time zone management: previous versions of TPE would set the time zone offset for the selected map location, but were not aware of daylight savings policies, meaning you had to set this yourself manually.

Given that landscape photographers, as a group, have a propensity to plan their travels well ahead and go to great lengths to get the shots they need in remote and hard to reach locations, it seemed important to minimize the chances of anyone getting the time of a critical shot wrong by an hour, just because they did not know the daylight savings policy of Patagonia in 2011, or similar.

TPE 0.7.5 takes care of this for you.

Also added is optional correction for observer altitide. The sun rises sooner and sets later when you’re in the mountains. I saw this first hand up at Dream Lake the other week, where the sun struck the top of the Flattop mountain a good 10 minutes or so before the calculated time of sunrise.

Of course, actual on-the-ground sunrise/sunset times are impacted by multiple factors that cannot be determined in advance by a computer, including barometric pressure and temperature which change refraction. So, take the times as a guide, and as always, leave sufficient time to get to your shooting location!

Various other fixes and tweaks included too. Have fun and let me know how it goes.

UPDATE: 0.7.6 released today – a few refinements and minor fixes. If you have 0.7.2 or later already installed, you’ll be prompted to update.
