Thanks for the replies Peldor and mrsid99.
I see what you mean about the colours. But the tones are just right. If I lighten them the colour may change their natural shades and I'll lose the feel of them. They look like they were taken on a damp and soggy day, or at least they do to me. Of course they weren't though. The rain is from me gently pressing the trigger on the hose-pipe so it threw out the odd small drop. You don't think I'd take a picture in the rain do you? :mrgreen:
I like them just how they are. But the more I think about it the more I want to brighten them a tad.
