I happened on a fascinating window reflection last week. Taking a photo of a stained glass window in the Queen Anne Cottage at Los Angeles County Arboretum, I ended up with something very unexpected.
These are the two windows in a photo taken directly in front of them which includes the metal mesh bars which protect them.
After snapping that shot, I realized I could see the windows better in the reflection in the mirror across the room.
Then I walked around the corner and took a picture of the windows through another window on the side. This was the result.
The red and white painted trim on the outside of the porch reflected back from the side window while the stained glass windows are brightly backlighted from sunlight shining through them.
