Hi!
Seems to me, and pardon my chutzpah, but...you already *have* contrast,
between the almost blown out open window highlights, and the darkest
shadows inside.
I think what is needed is more shadow detail!
Now, I don't know how you actually GET that, but that's how I call it...
Keith, your chutzpah is pardoned ;-). Nice choice of words though.
The window highlights are totally blown out - couldn't help it. I
intentionally went for darker image. That's how I felt wondering inside
depths of The Tower of London...
