I'm really in two minds as to whether you should process an image straight away, or wait a while.
On the one hand, if you want to capture the feeling *exactly* as you remember it, or present a precise replication of the scene your eyes saw, then probably the sooner the better. On the other, sometimes that emotional attachment can really limit the creative juices, as your mind partly remembers what it saw (or at least, what you thought you saw!). I love playing on the computer almost as much as I love getting out with my camera into the middle of nowhere, and I think that generally what I try to end up with is an emotive 'interpretation' of what I felt - does it really matter if the colours aren't quite right? Maybe the grass really was greener on the other side...
Photography is fundamentally an abstraction anyway - we're trying to present a 3D world seen by our eyes and interpreted by our brains as a rectangle that's been processed by our camera, our computer and then by another viewer with a whole lot of totally different life experiences... So long as you're not trying to claim that a shark really was in that puddle, or that a dress really is blue (or black?), what does it matter? Now I'll suffix this by saying that if you are going to claim an image as Nature, or Journalism, or Travel, then you have to be ethically responsible with how you treat your work or you undermine the integrity of the whole genre and photography suffers
But do you enjoy what you're looking at? Does it make you want to get up, explore, see something for yourself? Perfect.
And besides, it's pretty hard to make our beautiful countryside do anything but shine!
