I've got more shots of sunrises myself, like this one:
That was using my 70-300mm lens with my D40 and shooting (for once) in RAW mode. That helped pull some more subtlety out of the colour. Aperture f/8, shutter speed 1/500s and ISO 400 (see
full settings). The main challenge is not overexposing the sun and a large area round it while also underexposing most of the rest of the picture. This shot was just before the sun really got above the horizon.
Also, while waiting for that point where the sun itself is just hidden (or just about to hide) from view, keep an eye out for colours elsewhere. Here are a couple of shots I have taken at sunset, featuring clouds and buildings:
No filters... although some post-processing was done on the sunrise and the cathedral pictures.
