Channel M interview and Mega-Photo statistical information

On Tuesday 5 August 2008 I was interviewed on the Breakfast Show on Channel M, Manchester's dedicated tv station. I talked about the background to the Mega-Photo, how I took it and how it has highlighted the changes in Manchester. There is footage of people looking at the photo, and also a selection of photos from the archive. Click to view the video. See also statistical information further down the page.

Many thanks to Channel M www.channelm.co.uk.
