I have known Ben Ravilious, who runs Ultimateweb Ltd in Leicester, for some time through Leicester Civic Society, but I only recently became aware of this father, James Ravilious, who was an accomplished photographer.
Nice website at http://www.jamesravilious.com
There is a trailer option at http://banyak.co.uk/james-ravilious/
to whet your appetite for the film (DVD) entitled James Ravilious - A world in photographs.
