Now there will perhaps be a little vague and imprecise thoughts withought a straight thread. But anyway:-)
Is "beautifulness" something connected to the human thinking. Or could other species experience this feeling too?! We need to organize all information we are seeing or hearing, impressions we are becoming from all around us. We need to structure up the impressions to something we already know, otherwise it is hard for us to understand what it is. For example, when looking at a photography it could be for example geometrical shapes, or the melody scales and rythms in music. If it is too easy to organize the information, then the music gets only boring. There needs to be something that sticks out, irritates our intellect to say, but not as much as it gets too difficult to understand. (My father never understood the music I was listening to

) Here somewhere we could find the point where we experience "beauty" in the music etc. ?! And, if it is hard to reach the feeling of beautyfulness when we cannot understand, added that the nature probably often is too complicated, then I think the nature just goes out of what we can experience as beautiful. It is only simple parts of the nature which we can be beatiful, for example a flower or the sight of a mountain range. A scientist in zoology etc, with a trained intellect for his thema, can probably feel the beautifulness in another level than the common man.
Do we need to make the nature beautiful in our photograpy? Yes and no. It depend on what the images are for. I like to make images that are beautiful for me. And sometimes I make a photo only because I think it is something interesting. More complicated will it be when you which that other persons find you images interesting - then you probably need to make the images, so that the images hopefully are beautiful for the other persons.
Something I once have read over the thema "when is a forest beautiful?" - It depends of for whom. The person that likes to make sport or trekking in the nature, would probably see the diversified culture forest beautiful. But when the forest is totally wild for several hundred years it will be a hard effort for him to walk there. Probably this is not what i would feel as beautiful anymore. But the totally wild forest could be beautiful for a professor in entomology! On the other side, a person that has been growing up with forestry in the family and is now forest owner, for him is it probably beautiful to see high and straight pine trees without any bush in between.
And a little bonus in the end: Is beautifulness only something humans can experince? There was once in the television from a animal park in Sweden where they sometimes have music conserts. One of the zoo workers was asking if the loud music was not disturbing for the animals. And he told that it actually looks as there is types of music that attracts the lemurs, it looks as they are listening, but the schimpanzees prefered more rock style. This little story makes no proof but it is interesting.
