The only reason I am not active on here at the moment is because my computer is sick (I am on a borrowed one now, which has no programme for restorations).
I, too get disheartened sometimes when I have spent several hours restoring or colouring a photo to get either no acknowledgement or just a communal 'thanks'.
I am a complete amateur at restoration, which I took up after my husband died, to keep my brain and fingers active in my old age. I enjoy the feeling of satisfaction when restoring a really poor, creased image into a reasonable photo again. When you get a warm, appreciative thank you it really helps, makes it all worth while, even when I know there are some far better restorations, than mine.
What I find disheartening is when you have spent hours trying to restore a very poor image and all you get is a reply on the lines of, 'I thought this might be a problem' - no thanks for trying, it's certainly an improvement etc.
I will continue, when I can, because I love doing these restorations. I find the work therapeutic, because I am unable to walk very far and it gives me something to do when confined to my chair.
