Now that the National Trust allows photography within their buildings I have been able to take a few shots within my local property, Washington Old Hall. You are not allowed to use flash and there are some other restrictions, but this is a very welcome development. For those who do not know, Washington old hall is the ancestral home of George Washington.
The place is pretty dark inside, and, ideally, you need a tripod and the ability to take a series of shots at different exposures to cope with the very contrasty lighting. Without a tripod I wound the camera up to ISO1600 and hoped for the best!
