The framework for photojournalism has changed significantly over time. This has been significantly influenced by the changes in technology throughout the photographic age. Modern technology allows far greater access and mobility, and the ability to 'publish' images. So the role of the photojournalist has changed significantly.
I fell in love with photography in large part due to the amazing images photojournalists such as Don McCullin, Sebastiao Salagado etc were producing, of events that were happening in my lifetime. These were figures who would be sent by news agencies around the world to capture events, because they were individuals with talent for telling a story. But then, events were being told sometime after the fact mostly, not in 'real time' like today. So there was more time to consider images in terms of their own merits, not just the facts they were documenting. Photojournalism became an art form, imo. The power of the single image was immense, it had the ability to change the world. But with increasingly instantaneous information, the desire for such images waned, and with it, the importance of the individual photographer. Plus TV. Compare the Gulf Wars of the early 90s and 200s, with say WW2 or Vietnam; a major change in types of images used in print media, and how they were selected. Stills from FLIR cameras on helicopters and spy 'planes replaced images of human victims; war becamse sanitised and reduced to little more than computer game type imagery. I remember the stir images such as the burnt tank driver in Iraq caused public shock, because it 'humanised' the war too much for polite Western sensibilities. The appetite for such images was lost in favour of a carefully edited narrative, where nobody really dies and it's all good because 'our' side was winning hearts and minds...
In previous wars, for eg Vietnam, military leaders had little or no real control over the narrative a particular journalist was invested in. Hence the myriad highly critical images we saw from that conflict, which led to global condemnation of US military policy. By the 90s, governments worked side by side with the owners of media outlets, to strictly control the narrative in favour of themselves, so we saw far less such critical images. Think of how we are seeing so few images of the current Ukrainian conflict, or the events in Nagorno-Karabakh, etc. The notion of Truth in journalism has always been subjective, but now, it is far less objective than it ever was. And this isn't the fault of the individual journalists; editorial decisions are being made by politicians and media moguls, and not by genuine public interest. So the demise of the 'photojournalist' is a sad and disturbing reality of our modern times.
And now; here's some images of a pop star with not much clothing on! Newer, shinier, better.
