Describing art in terms of "genre" or "school" or any other systematic categorization or breakdown is not only useless, but also serves to rob the work of its true value. Rather than having a meaning, it now has a "bucket" to be lumped into along with other pieces with which it may have some things in common.
The answers are ambiguous – the image needs to be complex but not to a point of clutter, or it needs to be simple but not to a point of being too literal. It needs to have a message yet without the message being too obvious… or too obscure. Confused? If so, you have just learned an important lesson – art does not follow hard and fast rules, and thus transcends any attempt at a ubiquitous definition.
The beautiful scenery is there, but it cares not for pleasing composition or the quality of light at any moment in time. This is where the artist comes in, arranging in a frame the scattered elements into a story, anticipating and chasing the light, bringing it all together to create an evocative image capable of communicating the visual experience and impressing the grandeur of a fleeting moment on viewers for generations to come.
My goal as a person and, consequently, as a photographer, is to witness, participate in, and hopefully share the delicate beauty of wilderness – those moments in time when nature and spirit transcend the make-believe world of politics, economics, religious squabbles, fleeting fashion, mass “entertainment,” and other means of wasting the precious gift of thought and inspiration we are each endowed with.
