Always part of my "toolkit" – The Photographer's Ephemeris Review

This app has changed the way I plan my shots which are all outdoor and which require plan-ahead appointments. I now put my list of sites through TPE and find the structure's orientation, then the best time for lighting. Thanks to TPE's ability to change date and time of the map, I can review older photos and using the best ones, revisit the event and note things such as the position and angle of the sun at the time. And technical support is superb.
