You have taken some magnificent pictures. I was messing around with the primitive photo-editor on my computer and tried some effects from it on one of your images. I really like the way it turned out.
Hope it pleases. I think it would make a great letterhead image for you.
Hey Nick, just saw your inquiry. The photoedit (Picassa) program came with the (used) old XP computer, so I just mess around with some of the options, i.e., "sharpen", "fill light", "glow", and such stuff. This is the best I could do. Hope it suits.
