Richard, I tried increasing the saturation and that was a big improvement generally and improved the skin tones.
Andrew, I understand what you say but I still don't know how to crop to a precise number of pixels or size without changing the scale in photoshop - actually it's elements 10 that I use. Also, I don't know how to position an image on the canvas precisely - I had to do it by eye.
In this case, the original images were rather higgledy-piggledy so that I had to quite a lot of transformation using the perspective tool.
