I can't remember exactly how I bumped into this blog about Mexico but I find it fascinating. It's written by a man in Salamanca who evidently travels all over the country, visiting and doing research about various places and doing some pretty interesting photography. There's not much personal information in the blog and I've asked him for some details: Is he a historian, photographer, artist, professor?
The blog is in Spanish and the level of his grammar and vocabulary is definitely not entry level, but even if you can't understand it all, his photographs, evidently taken with a small pocket camera, are impressive.
Recently he posted a short essay about circles and then a series of photos about circles, from a rose window in a cathedral to basins and drain holes. Cool stuff:
