Sunset

A striking sunset this evening. The light was concentrated in a small part of the northern sky. Soon our sunsets will be moving round more to the west, but I do like the late evening northern ones.

Does anyone have a good suggestion on how to get realistic sunset colours? My camera's viewfinder never matches the actual scene, regardless of the white balance setting, and I can't match what I remember in post processing. (This one has been tweaked with a bit of On1 Effects Magic Sunset, and then the orange hue shifted a little to red.)
