My thinking is that trying to classify photography into “reality photography” and “conceptual photography” won’t work because there is no such thing as reality photography. Because photographic images often have many similarities to what we see with our eyes, we get tricked into thinking of documentary photographs as showing “reality.”
But even the most representational images exist as an abstraction from reality. First, and perhaps most obvious, the photographer chooses what to include and what to exclude from the frame. Reality extends far beyond the limits of image edges. It is possible to make photographs that are deliberately misleading about “reality” simply by excluding important things from the image. Then there is the issue of color. Many people accept black and white news images or landscape images as though they show reality. But the world comes in color. Conversion to black and white can be done many different ways and can show things very differently than our eyes see. The dynamic range out in the world usually exceeds the range that can be printed, so various abstractions are required to compress luminosity into something that can be shown. Then we have the matter of depth of field, often used to show part of the image sharply and part not sharp, while “reality” does not come blurred that way visually. Selective focus can be an artistic technique that directs our attention in a way that suggests how we might direct our attention in person, but it is not how reality looks in person. Of course, photographers also have to pay attention to perspective, overlap of objects, relative positions, and lens effects when making the abstraction from three dimensional reality to a two dimensional image. Well-selected shadows and highlights in our two dimensional images give a visual illusion that reminds us of three dimensional reality. Poorly selected positioning can make a tree appear to grow out of the bride’s head. Even extracting an image from the digital data generated by a camera sensor requires lots of translation (see different outcomes from different raw converters, including the default converter used if you don’t shoot “raw”), just as converting an undeveloped negative into a positive print or slide required many decisions that can change the output.
Many times, the concern lurking in these discussions boils down to varying degrees of comfort or discomfort with specific kinds of combining multiple different images and adding elements not in the original capture. Compositing, drawing, text, textures, and similar techniques evoke concern. Interestingly, combining images for panoramas usually escapes criticism.
Some try to define limits, beyond which a photograph is no longer a photograph. I haven’t seen general agreement arising from that approach, and I’m not expecting such agreement to happen. Some try to categorize images by the photographer’s intent (document a place or event, evoke emotions, make us laugh, inform us, make us think, amaze us, trick us, just create something unique and/or beautiful, and others). But photographers may have multiple intents in making their images.
For me, the best resolution has been to enjoy the very wide range of images made with all sorts of techniques, pay little attention to images that don’t speak to me currently, appreciate the skills and expertise of others who may use techniques far beyond my skills, and be comfortable following my own path when I make my photographic images.
