You can get good images of Yosemite Chapel in several locations (see A on the map). I like getting close to the chapel and capturing it against the cliffs with Sentinel Rock in the background. You can also go across the road and photograph the chapel with Half Dome, or use a longer lens and compress it against the cliffs.
The best location from which to photograph the Yosemite Chapel: (A) the grounds around the chapel. Other photo ops: (1) Ahwahnee Hotel, (11) Indian Village, (22) Three Brothers, (29) Yosemite Falls.
