Thanks to all the replies. Yeah, the sharpening is I guess mostly for print, but in this digital age I also like having them for the web too, to share with friends and family, and on this site.
No doubt at all it's a slow learning curve for me. But as basic as this may all seem to others, I've already learned a hell of a lot in the short time on this site, so it's working. Maybe one day I'll get there...
Thanks again everyone! Hoping to get some snaps on the weekend to play with... if I can stay away from too many of those naughty, naughty beers on Saturday night.
