The flight of 23 locks on the Leeds & Liverpool canal, leading down through Ince to Wigan, is the true road to Wigan Pier. This massive undertaking, which lowers the canal by all of 215 feet, is one of the most powerful evocations of the industrial revolution that transformed Britain, particularly this section of South Lancashire, in the 18th century.
Propped up in bed with my iPad this morning, I was impressed by Eric Kim's very plausible case for taking a photograph every day. He is surely right that the routine of always having a camera in the bag and remembering to take one photograph every day is the key to improvement.

We are most of us quite familiar with crop factor and the adjustment of focal length when using APS-C, Micro Four Thirds or 1in sensors. The maths is easy: 1.5, 2.0 and 2.7 covers these three options in relation to the 1:1 of the full-frame sensor. But what effect does sensor size have on aperture or sensitivity? It's all a question of equivalence.
