Hi Kaz,
I'm pleased that you like it

I have only been doing (my version of) photo restoration for a few months and it's a case of "learn on the job" for me. I have a try at most photos on RC, and only post the ones I think are sortof OK (some are total failures

)
I have five different "restoration" programs which were on my second hand computer when I bought it. Of course - I have no instructions for any of them so it's all trial and error

Just practice, practice, practice and you'll be helping others on here very soon.
Good Luck
Di
