My partner Kim has just created her new photography blog site at: http://www.kimbyrne.co.uk/. Her first article is about long exposure photography using a 10 stop filter. It has a handy chart for converting between exposure values. The article is at: http://www.kimbyrne.co.uk/landscape/long-exposure-with-a-10-stop-filter.
The BBC has published a fascinating slide show of old aerial images of Britain.
