Elected to post a screenshot of what I did, so I could put the histogram up for regard:
I modified the contrast and whitebalance first, to get a ‘regular’ image. Note the histogram, the white balance is simply the adjustment of the red and blue multipliers to make those right-hand points all align with green.
The curve is my attempt at “poor man’s layers”, desaturating the background and punching up the foreground, which already have some separation by tone. The saturation tool is just a feeble-minded attempt to take that further.
By way of explanation, the displayed image is the product of all the tools, indicated by the checkbox at the end of the tool chain. The tool displayed in the parameters pane is the one selected in the tool list, which in this case is not the end of the chain. Tools are applied to the raw image in order, top-to-bottom.
