Yes, I have been trying to categorize the different types of photography that are popular and not so popular.
Most common groups:
PROOF PHOTOGRAPHS
Lots of images of people standing and smiling in front of monuments. Pictures of your family vacation. A kinder term might be mementos. But they are a form of documenting that ‘you were there.’ Or that you took the ride at xyz amusement park. Or even that you and your sweetheart made love in the barn. t. Maybe it’s what they used to call a Kodak moment. Maybe it’s just something that brings you back to that time.
For the most part these images are only evocative to the people in the picture or the person that took the picture. However, every once in a while, if these proof photographs are also connected with an historic event, they become universal. Examples might be soldiers posing for each other just about anywhere during wartime.
And on top of that, even these simple pictures of the family will, with time, become more interesting. If you go back to look at were are now fairly inane images of the kids and pet that were taken two hundred years ago – voila – they become true documents because you get to see what the world was like back then: the fashions, the cars, the homes.
CURRENT DOCUMENTARY
Images of historic events and the people involved that the average person doesn’t have access to. This is what is going on in the xyz region today. Very few people have been able to actually see this for themselves. And photography still serves that purpose.
BEAUTY IN THE IMAGE (Is it a postcard image? Is it simply beautiful? Another sunset? )
With the right subject, lighting, and composition – photographs can be as beautiful and mysterious as any other great form of art. It’s true that the 5000 cell phone pictures multiplied by 1 billion people will produce beautiful evocative images; and there is a class of editor who’s job it now is to sift through all this junk looking for the few images that are sellable. It’s somewhat equivalent to the million typing monkeys who will in some time period approaching the infinite produce Hamlet, or something worth reading.
There will be (and are) gatekeepers to separate the beautiful from the banal. Someone has to do it or we’ll be overrun with sunsets and sunrises.
The art photographer may not do much better. As Matt said, we are happy to get 10 really good images in a year, but our standards are not the same.
EROTIC PHOTOGRAPHY
Unfortunately, a large number of people are going to end up reading this dry category description because of a search engine. Nevertheless, the erotic photograph has a history that begins with photography, and that goes back to cave paintings. It may just be the most popular and most lucrative form of photography. I’ll have to take the Supreme Courts famous declaration: I know it when I see it. Of course, that is just dumb, since what is erotic to one person is a complete snooze to another. Nevertheless, it should be listed as an important category.
COMMERCIAL PHOTOGRAPHY
This is one of the easiest categories to define. The images are of products (human or non-human) with a purpose to promote the product and make the viewer want to buy the thing, or see the movie, or whatever. They can also be artistic, but the primary purpose is to sell something other than the photograph.
I find myself moving in and out of all these categories. I admit to being least comfortable in the pure commercial field, but this usually pays the best since if done well it can make money for the producer.
SCIENTIFIC PHOTOGRAPHY
Suggested by a reader, to include anything from geothermal mapping to photographs used to search for cracks or potential cracks in Hoover Dam. Photography with a technical / scientific purpose.
Not included as categories: Found Art. You search through garbage or wherever and find photographs. You then display them. Or you make a collage with them. Whatever. It’s removed from the original category of the photograph by the artists’ intentions.
Frankly, all these categories (are there more?) have soft edges and run into each other. You can clean them up if you want to make sub-categories. But this is more useful for me. Nature photography, for example, is a common category, but it can easily fall under BEAUTIFUL PHOTOGRAPHY or even SCIENTIFIC PHOTOGRAPHY, or PROOF PHOTOGRAPHY. It depends on the skill and purpose of the photographer. The truth is that no one can define art, though you and anyone else can take a crack at it. It is elusive. It goes in and out of favor. But I am thinking that in the case of photography, it can be plugged into one of these categories.
But the main kick for me (other than some of the technical stuff I get into) is the feeling that I’ve caught something that is just hard to describe in words and that will probably never exist again. One example of this sort of work is shown below. It is the burnt out building in Brooklyn (Manhattan on the other side) where a mad artist lived for a while. I was brought there by a painter friend and was glad to have my Mamiya 6 (medium format film) camera with me.
Of course it is completely unsellable. Nevertheless, I post it now and then because it seems to demonstrate one aspect of the power of photography that means something to me.







There is another (sub?) class of proof photographer, although I’m not sure how numerous, that utilizes ‘found’ photos to help illustrate an era that he/she can profit from through ongoing presentations (slide shows, etc.). One in particular is a fellow by the name of Charles Phoenix, whose work can be seen at:http://www.charlesphoenix.com/category/slide-of-the-week/
While not a true photographer, perhaps photo historian is more accurate, nevertheless he uses photography as a medium for his and others enlightenment, and to provide himself a living in the meantime.
How about another category – Technical or Forensic photography. I’m thinking anything from a crime scenes through medical imaging to technical work like flourescent dye penetration inspection of mechanical parts. Aerial survey photography has led to google earth and the street view application.
I recently read an article about early 20th century crime scene photos from the NYPD. The editor had selected views of apartments from murder investigations. There were all sorts of personal items lying about giving clues to the victim’s lives. Not unlike your shot of the artist’s place.
Does the ease of taking and sharing these “proof photographs” make them more or less relevant than the old kodak moment? The early 21st century will certainly leave a massive digital fossil record of our lives for future students of culture and history.
Well, it wouldn’t be unsellable if you were a big-shot trendy artiste exhibiting in cutting-edge Art Galleries, or being shown at the Getty.
