As a general rule in the usual circumstances, as I am advised by the unhinged Québécois and Steve Isaac, the master blaster in black and white, we deal with a difference of the equivalent of two f-stops between the brightness in the shade and the brightness in the open sun. (That was not the most elegant way to express what I was trying to express, but it will have to do until I think of a better way to say it.) Here there is a significantly bigger spread, especially at midday. Even the best photographers struggle with that in the great state of Guanajuato. Over-exposed back lit areas, washed out skies, blacked out areas in the shade, etc.
On the other hand–and the reason that I bring the subject up–one does get these nice, crisp shadows to play with.
And by the way, these photos are not a violation of my oath never to publish any more photographs of churches in this blog. This building never officially became a church. As it stands, it is merely another piece of nondescript, abandoned construction. That is the loophole of which I am availing myself this time.
