HDR LightMap: Day Burg Hohenzollern

Name: Day_Burg_Hohenzollern

This daylight HDRI light map was captured in at the chapel of castle Burg HohenZollern about 45mins from Stuggart Germany. Time of capture was around 12:30pm.
This map was captured handheld while I was on holiday (after FMX 2012).  Forgive the lack of a gray or macbeth since I was not carrying my normal gear/tripod with me.  As a result of not having a tripod, AEB range was constrained to avoid any long exposure frames given I was hand holding. This caused one of the lights to clip but it was not the dominant key light in the scene.
