Everyone's talking about the CCD look and the film look — but what are they, do they actually exist, and can you tell them apart? Three images, three different technologies, one style. See if you can guess which is which.

Six woodlands across four blogs and over a thousand still to explore. The final part of the series steps back from the trees — accessibility, seasons, sounds, and one thing that genuinely needs saying about dog walkers in ancient woodland.

Ashridge contains more ancient and veteran trees than any other National Trust property in the country. Bisham Woods may have inspired the Wild Wood in Wind in the Willows. Two extraordinary woodlands at opposite ends of the Chilterns, and between them enough subject matter to keep a photographer busy for years.

Penn Wood nearly became a golf course. Burnham Beeches hid 100,000 military vehicles under its canopy before D-Day. Two heavyweight ancient woodlands, two very different characters, and between them some of the finest woodland photography conditions in the Chiltern Hills.

Black and white photographers whose work I admire and return to — Edwin Smith, James Ravilious, Fay Godwin, Don McCullin, Frank Meadow Sutcliffe, Adrian Vila and Christine Wilson — and why I make a point of not looking at them too closely before picking up my own camera.

The Sony A700 is a camera that was built to be used — and that's exactly why it still earns its place in my kit today. A second body that keeps me in the same Sony A-mount system, fits in the hip pack, and delivers smoother black and white JPEGs than anything I'd spend ten times the price on. Sometimes old is still good enough, even today.
