I just want to post this link:http://www.raymentkirbycameras.co.uk/index.htm Click on 'Workshop' for six detailed and well illustrated and documented sections on building a 5x4 in. view camera. I have just discovered it and I found the information to be very useful. I wish I had found it before I built my camera rather than after. - I feel a new one being planned right now! I'm sure many of you are already aware of this but I thought I would mention it for those who may not have seen it. Steve.
