A few more examples of Cézanne's lesson that paintings (and photos) are flat. The lesson does not only apply to landscapes (also think of Martin Kers's remark that landscape pictures should not include the horizon if you don't really need it) or cityscapes, but also to architectural details, or all kinds of objects.
(Of course there is much more that can be learned from Cézanne, but one thing at a time, please!)
Using this trick makes for photos with a different theme than most standard pictures: they direct attention away from the landscape, building or object itself and towards structures, patterns, repetition, rhythm. They become less of a representation and more of a 2D-plane which should please the viewer with its colours, lines, etc. And I like if it also sets a bit of a riddle to he viewer: What do I see? On the one hand, I like it to see such riddle solved. On the other hand, it does not really matter what is being represented. The only photographic question is how it--whatever 'it' is--is brougth into the picture. Somehow, in such pictures I often have a preference for verticals and horizontals--from Cézanne to Mondriaan. But he'll have to wait to another time.
(And sorry if the three pictures do not nicely line up at the left margin as I wanted them; I'll have to learn a bit more about lay-out tricks in blogging...)
