Ok, slightly related post here:

I have been thinking about sneaking a model into the Fox Talbot Museum of Photography in Lacock, just down the road from me.  http://www.r-cube.co.uk/fox-talbot/history.html

In order to get a shot in front of the lattice window, which is famously alledged to be the first photograph ever taken.  But I think it will be easier to do a layers edit. Any thoughts, like am I going mad?
