Wow, stunning photos!
I don't have much talent in this area. One of my friends used to help me and such since she specialises in digital photography. So unfortunately I can't give you any tips. A couple of years ago I used to like making my photos red by putting my finger over the flash source. Sure was funny.
Though it was rather silly.
Lovely shots, Ledgem. Made sure you share with us more.
