Here is a lovely image posted by Russell on a web forum, but he had to photograph it under hard lighting with haze in the background. The exposure was 1/500", F/9 at ISO 320 using the zoom at 119mm. I said it would look great with a bit of post-processing and he invited me to try, providing I detailed the steps I took.
But before I started, I always want to consider the image and the story that it could tell.
This is one of the great sights of the world - a wall that stretches for thousands of miles and can be seen from space - and so its abrupt ending, on the right side of the picture, did not convey this to me. I think Russell found this interesting and included it in the image, but I would crop it off to give the impression that this Wall goes on for ever. The other advantage of this crop is to position the main tower more towards a 3rd position and if we remove some of the bottom foreground, then the horizontal walkway would also be positioned on a 3rd.
that because of high jpeg compression there are artifacts, especially in the
sky, that would not be there in a full size image.
For fun (and out of interest to see what would result and because I got a bit 'carried away') I used 11 different methods of adjusting this image
You can compare them by following this link which will open in a new window allowing you to flick between them. When you've seen them, then close the new window.
It should be born in mind that interpreting an image is a personal thing and as I did not see this wonderful sight, I may have made the grass too green or the wall too red. However the above corrections are just the first step in processing an image - so I've taken what I consider to be the best method and further processed it as follows.

Hope you enjoyed this experiment, I certainly learnt a lot.
