Objectivity is a fig leaf that the establishment tries to put over the bits it’s embarrassed about, why on earth would a European socialist Jew try to be objective about the Spanish civil war?
I believe your words to be poorly chosen and your reasoning to be suspect -- simplistically smearing the whole history of photojournalism, in tactics very similar to those you purport to deplore.
I suppose Capa was not objective with his D Day photos as well, are you suggesting that the same photographer cover "both" sides in a shooting war simultaneously?
I do not think Franco and his Nazi/Fascist allies overall are favorably recounted in history along with the rest of non- "European socialist Jews" historians' general accounts of Fascism of this period.
In journalism, the goal was to be objective in that words and photos portray as accurately as possible what actually occurred at the time of the event, while being a bystander or witness if you will. If you can interject some art in to it, you may be considered a better photographer or writer. Observing something changes it, but the degree is what is important. I doubt that the Zapruder film changed much of what really happened in Dallas. I do not know if Abraham Zapruder was a socialist, never occurred to me to think much about it.
With the alleged, by some, "staged" shot of the soldier dying, Capa may have been in the process of shooting one thing, troops training, but by all accounts the soldier did die by enemy fire at that moment. His name is known and witnesses accounts recorded, some quite recently. I somehow doubt the sniper knew Capa was there and vice versa.
The lines today are certainly blurred between opinion and fact in terms of contemporary reportage, leaving what passes today in all areas of journalism in a different view. Interesting that this comes up the week that Walter Cronkite dies. I really have no other examples handy with any confidence of straight news.
At the very least it is a style change, at the worst "news" today is simply an op ed story marketed sometimes as news. Unfortunately much of photography is so common and photographers numerous as to almost create the event it is supposed to cover.
This does not change what happened in front of the cameras during many historic moments, nor does it release observers from thinking critically regarding the data they are presented with.
Sorry for the long post.
