I look at hundreds of photos every day for my international news page. I also have taken a few for the newspaper.
These are my notes:
1. A good photograph might not be a good news photograph. That is, an image may be very creative, out of the ordinary and stand on its own as an art piece but wouldn't convey the information needed to accompany a news item.
2. When I have more than one candidate for a news item, I will either choose the most clear one, where the reader will have no trouble understanding what's going on, or the most creative one. The former will give me the feeling that I am doing my job well, that is informing the reader visually and not only mentally. The latter, makes me feel like I am treating the reader to something special, like a dish with an extraordinary taste. One would fill his "stomach" and the other his "taste buds".
3. Creative photographs stand on their own and can be used again in the future, displayed by themselves as art pieces, or sum up the whole situation. Simple "visual news" are there only to accompany the news item and in many cases are unnecessary and give no more information than the text. For example, a photograph of a wrecked car by a bomb in Baghdad doesn't even need to be there as the reader probably has seen hundreds similar ones already and the text itself is enough for the information. A close up of a crying child done as an artistic portrait, not only sums up all the horror and misery of the entire conflict, but works in many other ways: Can be used again as I mentioned, it creates a more intimate connection with the subject of the news, goes beyong reportage and more towards an understanding of humanity. Like Salgado's work or any other master of photojournalism.
4. As I have taken photographs myself, for one thing, I think like an artist not like a photojournalist. Whether it was the trip to Martinique or the demonstration, I brought the Hasselblad, used film and my every photo was thought about, composed carefully and my pressing of the shutter button was like a sniper taking a headshot. The other photojournalists brought their digital machine guns and just aimed in the general direction, keeping the trigger pressed and only thinking of supplying the news page fodder.
5. All of my photographs that I have taken with an artistic mind (usually with the Hasselblad) can be shown on their own and can be part of my artistic portfolio. Yet, I also brought a Nikon (film or digital) for those "use once" photos of small politians shaking hands, etc.
6. To sum it up: a typical photojournalistic photo is "use once then throw away" when consumed, usuable only in the archive when needing something to accompany the text. Those photographs are merely fillers are rarely being payed attention by the photographers, the journalists, the editor or the reader. A more artistic photograph is more valuable, stands on its own and often can become iconic of an event or even an era.
The photograph of the bloody face of a student in the pavement with the boot of a riot officer next to him became iconic of the student demonstrations in Greece and was published in many newspapers in the front page, sometimes even more than once.
7. A good photojournalist works as a journalist and as an artist and usually for himself. A typical photojournalist is just a photographer, working for the paycheck.
