To create a fine-art photograph, the key is to have a quality of light throughout which unifies the whole image. Alfred Stieglitz, the father of fine-art photography, was doing this already at the beginning of the 20th century. We need to see more craftmanship like that today.
Here is an image that may illustrate what I mean. The diffuse light coming from the overcast sky this particular day had a warm quality, yet not altogether inviting. This gave the abandoned home a sense of having been lived in, yet deserted and alone. Light means everything when composing an image, and to ignore it is to ignore the ground root of all photographic imagery.
