Cheers Russell ( btw, that is my surname

).
Spent yesterday at work ( some free time ) playing with old images and a couple of hours last night on more. Didn't realise there was so much good info and detail in many of my early pics. Also got a better understanding of the processes involved and once I had my head around the two limit points I could skip the first levels operation and just pick my points at the curves toolbox and go on from there.
It is only specific to Photoshop though so for those without it they can download it legally free from
www.snapfiles.com in the Free, graphics section. This is the free PS2 version Adobe released last year for public use and includes the license string. It works perfectly with your tutorial and for anyone wth any graphics skills is not too hard to understand.
I'll post up a few re-processed images later once I'm happy with them.
I've already recommended your link to another new member with reference to yourself. Once again thanks for the very valuable info and keep up the good work.
