I've seen plenty of photos like this before and I've always liked them. They're usually warmer colours and they seem to have a bit of a haze to them.
What sort of post production is being done to this photo? I'm mostly interested in the colour and haze effect. Is the vibrance turned down in these photos? It's seems to be yellow+ and magenta+? Does the photo have to be initially taken in a certain way, or can this sort of post processing be achieved on most photos? Do you know of any tutorials out there that explain this processing?
