An easy image?

Well, I had better show you what I had done with this image

My first attempt was to make it as colourful as possible - the Gregs know that I'm into saturated colours

But on reflection the next day, I thought this was the wrong approach and I needed a more neutral rendition.

So I lifted the shadows, by a simple rgb curve (35:83 & 80:144) masked by an inverted copy of the image - this almost gave a presentable image, with a touch of a red tint.
So I curved again, this time for colour in Lab
I finally added warmth and emphasis by blurring, yes blurring, the image, masked by 'find edges' to leave enough contrast in the columns etc.

- completely different to my 1st go.  This is what I really enjoy about pp-ing, one can change the whole mood of an image by simple curves.
