......... I did some quick playing with levels and curves, contrast and came close but still not as good. ....
You are very welcome Tom and Mongo is glad you are happy with the changes.
In addition to the tools you used, also try (in photoshop if that is what you are using or similar), "selective colour" utilising within that tool , the white, neutral and black channels in turn and add or subtract black as needed. Selective colour is found in Image - Adjustments - selective colour.
also consider the careful use of some "luminance" which is found in Image - Adjustments - replace colour.
Lastly and most importantly, Mongo found you cannot generally get the best results if you try and do the adjustments as a whole over the entire image. For this reason, even though it may be a lot more work, Mongo often works on each segment of the image separately e.g each arm, the face, the background, each segment of her dress etc.
hope this assists.
