Hello!
For what it is worth. The expression "sun angle" reminded me of this nice site: "Sun or Moon Altitude/Azimuth Table"
http://aa.usno.navy.mil/data/docs/AltAz.php
If one knows the location (coordinates) and (even approximate) date one can use the site to tabulate sun angle and direction for one day (any day and year) in required intervals. If sun angle can be determinated from photo then one can deduct the time (remember GMT +/- x hr) and sun (shadow) direction, too. Accuracy depends of the angle determination error and time interval in the table (you can use even 1 minute intervals).
When sun/shadow direction is clear it does help in putting the photo setting on map too. I have used this site several times since an Estonian friend suggested it years ago.
Cheers,
Kari
