Went to an old church on Campbell and River here in Tucson.
Many possible paintings there, took tons of pics with my new Cannon Rebel.
The shadows were perfect even if they did move the whole time.
The stucco walls were not white, they reflected the brick floor or the sky or the trees. After looking so hard it felt like you were going crazy, they are just white walls!
Took 4 hours using Alkyds on a 8 x 10 inch panel.
