Alright, I've got an idea thanks to Richie's daily pictures. Everyone processes their pictures differently (and each result is as right as any other) I thought it'd be interesting to post up a picture I've processed and post up the RAW file so anyone who feels like it can have a play with it and show how THEY would process the file.
Here is a quick example of what sparked the idea, Richie had a picture of Durham (I think it was) castle and it had a lot of yellow street lights, personally I remove as much as possible:

But it is a very much personal choice.
So, here goes my chosen image to see how you lot might process it:

and it looks like this: (before processing)
I'll post up how I did it later in the week if some others want to play along.
Feel free to post your own RAW files to see what others do with them BTW.
