...if images are produced -by the numbers- ie: consistant processing, histograms, adjustments, etc, especially in landscapes, and it's just a recording of conditions. Other than composition, what would be the difference from them being shot by a machine? Doesn't seem to be any sense to it unless there's some type of individual expression brought about, and how could that be done?
That's why Henri Cartier-Bresson referred to photography as "the artless art". He meant that the gear, materials, and processes made photography very easy, and that the skills necessary to create a technically competent photograph were fairly easily learned (compared to most other arts) by anyone who chose to make the effort. All that's left is the photographer's eye and mind, and the aesthetic side of the photo. Composition is a big part of that, but there are other considerations and choices too.
Put your camera on "green square" and the default in-camera processing, and go out photographing only thinking about composition. Take the files straight from the camera, and drop them off at a lab for uncorrected printing. While some of the photos will come out fine (composition and subject choice are major aspects of whether a photo will be percieved as good or not) on most I bet you'll be able to see where the finished print could have been improved if you had been more involved in making choices in exposure, processing, and printing.
There are a lot of choices that can be made between adjusting exposure to picking the paper type for the print. I can't speak for anyone else, but at the point I'm at in my study of photography many of these decisions are made without really thinking about it. It's just become intuitive as I consider the scene before me, and how I want it to look in print.
With film it's advantageous to work consistantly and by the numbers, at least as far as exposure and processing goes. It has to be planned in advance as it's very difficult to see the changes being made during processing, and they are permanent. Even so I'll have the opportunity to make changes during the printing stage. A friend of mine who shot landscape with 4x5 E6 would take 3 identical shots of everything. He'd drop the 1st sheet off at the lab, and see how it turned out with the standard E6 processing. If he needed to adjust the processing he could drop off the next sheet with processing change instructions, and fine tune it even further with the final sheet.
With digital I process by inspection; if I goof up, or try something that doesn't work out I just start over. I pay attention to the numbers, they tell me useful info, but I trust my eye more (as long as I understand or minimize the differences between how the photo looks on my monitor and how the photo will look on paper). While digital can seem math and number oriented, I actually feel that I have many more creative choices with digital than I did with film. So many more that even though I loved my traditional darkroom in the past there was no way it was going to satisfy me in the future.
Long before Ansel Adams was a photographer, he liked hiking in nature. He carried a simple box camera, and took photos of the places he visited. He was very disappointed in how the photographs he got back from the lab didn't convey the sense of grandeur he felt when actually at the location. He was perplexed that his eye and mind could see the world one way, and the camera would record it very differently. He decided to study photography because he wanted to create photographs that would give the viewer a sense of the feeling he felt when actually at the location.
Good reading would be the first chapter of Ansel Adams' book "The Camera" where he discusses visualization. Another good book by Adams is "The Making of 40 Photographs". He gives several examples of how a straight contact print from the neg doesn't look anything like the final print (Moonrise over Hernandez, NM is one). Google the terms "visualization", "previsualization" and "expressive print" (add the keyword photography to help define the search) for articles by various photographers.
"The use of the term "art medium" is, to say the least, misleading, for it is the artist that creates a work of art not the medium. It is the artist in photography that gives form to content by a distillation of ideas, thought, experience, insight and understanding." -Edward Steichen
"Dodging and burning are steps to take care of mistakes God made in establishing tonal relationships!" -Ansel Adams
