Seeking "inspiration" through mimicry does not produce inspired work. It produces, at best, something to do. (i.e. "I think I'll take some close-up snaps of flowers today" is not a statement of inspiration.) Also while the Web can be informative it's inarguably a very weak medium for experiencing art in general, photography included.
I agree with Asher. Become interested in bodies of photographic work and their creators. Make every effort to see original prints or, failing that, see the work reproduced in books. Failing that, visit the photographers' own sites (or the sites of galleries or organizations that have a special interest in that photographer's work).
Rachel,
Ken puts it very well. One needs immersion and then some passion. Tim Armes is a mountaineer because he's obsessed with the earth and the sky and everything in between. He gets intimate in one subject and then photographs that series well. He doesn't copy, he just gets a need and works hard to express it.
Look
here. His "Artisans" series involved getting to know and
enter the world of dedicated workers and try to engrave that experience in an image. He's not flitting here and there or snapping. His "Still Life & Products" collections of series has a group on just one abandoned bicycle. Look at that, not because it's a "good web site", (although it is), rather to illustrate Ken's point about passion and focus. Your interest in your river was one such good project but that is difficult because you don't have, as yet, set of limits on choosing a subject and composition. That's needed to craft one unit of art. Knowing what to include and what to exclude can be difficult as one needs "enough", (and often less than I happen to think is needed), but
exclude what adds nothing or, worse, detracts. For that, I think, Ken's idea of drawing/ sketching is a great remedy to try out.
To the passion one can add craft, but without the engine of the former, we are a snappers, working with mimicry or even when really experienced, may rise to highly "talented technicians" but not much more than that. At least the "talented technician" produces works that grab attention to admire and then
we might bring our own imagination to that work to make it live for us.
Back to the beginning again, bookmark Tim's website and a few others from OPF, but choose for yourself one exhibition, one photographer or theme and one book. Then a drawing class!
Where you grasp and engage life is your route to being stimulated to have needs to express. The Web? For mutual support, to solve problems and to show others your work.
