Great landscape photographers, like the great landscape artists before them, such as Turner and Constable, try to capture the essence of a place, what makes it appeal to them and use form, colour, composition and light to convey a particular meaning or mood. The result is their visualization of a scene. The "technical" elements and combined with an idea within their head about what image they are trying to produce and mood or symbolic meaning they wish to convey. For example stormy skies give a moody, threatening feel to an image or a winding road conveys the meaning of a journey.
Simplicity is the key and many great shots reduce the landscape (or parts of it) to a few simple components.
Look at great landscapes (either photos or paintings) and try to learn what makes them great, not technically but in terms of meaning, message or visualization. I know I will in future.
