It is great to see other people’s ideas, and to see how an image can be so well manipulated to create such different "feels", many thanks to everyone for their valuable input.
Peggysue, I really like the way you have focused the image on the dogs themselves and it is interesting how removing other, potentially distracting, elements makes it much more of a portrait. (The collies are mine - meet Gryphon, Shep and Wisp. There are not many pets in my area, so they will have to be my main subjects for now!)
Julie, I really like this textured, aged look, it is very effective, and yas you say, enhances the atmosphere. I have a long way to go before I am even going to attempt this, but did you create the texture yourself?
