Just for fun really…
When taking sunset photographs, I like to look and study how the light affects and interacts with the landscape and not just at the colours of the sunset though of course this plays a major part in the composition. I often like to pick out specific features of the foreground that compliment the colours of the setting sun; the light of the setting sun reflecting on stones, the colours of the vegetation, etc.
Sometimes I am thinking in black and white and shades of grey and / or sepia in which case the way the cloud formations contrast with the overall scene is very important.
I try to shoot using as smaller aperture / slower shutter combination as I can get away with, which sometimes means using a tripod. For me, simplicity is the key.
