I noticed that one of the tutorials requested was "Creating sunset effects from normal daytime photos". I wanted to do this with a couple of my own images the other day, and found quite a neat way of creating a dramatic effect with a Gradient Map. Anyhow, I've written it up as a tutorial here:

Although I've been using Photoshop for some time, this is the first tutorial I've written so I hope you won't be too hard on me!
