I am an amateur photographer, and my writing on this site is mainly an attempt to explain aspects of photography to myself.

In my day-job as a university researcher, I design, build and operate cutting-edge astronomical instruments. (That said, astronomical optics are in some ways easier than photographic optics, as astronomical objects are very much at infinity and we don’t have to worry about depth of focus so much.)

I grew up in England, but spent my twenties in the USA, my thirties in a provincial city in Mexico, and am currently spending my forties in Mexico City.
