Wish I'd spotted that. Very nice - although IMO you've desaturated the wall too much.

Thanks Rich, have re-done the shot, is this any better?

Yes, much better. Don't you think?

I am undecided, the original shot was inspired by the part in The Wizard of Oz where she (Dorothy) opens the door after crashing on Oz, the house it still mono but Oz is all in colour.

But yes, it still works having some colour in the foreground
