Central Tokyo is just starting to turn. The trees are turning an amazing mix of red, yellow, and green. It's a beautiful time of year, and it seems such a shame to have to work in an office during daylight hours so bright and vivid as this.

With a polarising filter, the sky is really vivid

In around a week, autumn will be all around us. The above tree, central to the campus here at the University of Tokyo, turns an amazing yellow by the end of the year. I estimate that in the first week of december, this area of the campus will be yellow, if previous years are anything to go by.

However, next week, I'll be in Okinawa for work - when I return I think it'll be impossible to walk around Tokyo without rustling in leaves!

Leaves weren't the only thing turning
