If you like taking pictures at the sunset, I have two tips.
First - do it at the right time
In photography books, they call it "the magic hour". It happens two times a day, just before and after sunrise, and just before and after sunset.
The light during the magic hour is magic indeed. The word which is misleading in this term is an "hour".
It's much shorter than that, maybe five minutes or so, depending on the weather.
Let me illustrate.
That's the perfect time during today - 7.30 P.M.. The city lighted up with colors, the sky is dark blue, giving a nice shade to all of a scene.
Just a few minutes, but the differences are vast.
Second - forget about the sun
Shooting directly at the sun setting down is great, but all the landscape is nearly black, with no details whatsoever. Besides, everybody is doing this, so there's a gazillion of identical pictures. Probably in your albums you have at least a few as well.
So that you are looking away from the sun.
Last rays of light are very soft and warm, casting long, nice shadows. Such a lighting makes practically any object stand out.
Even snapshots, like this, catch the attention and set a mood
