Would using selenium intensifier to make a thin negative printable be considered manipulation? What about burning and dodging to make "valuable" objects &c in a scene be considered manipulation? What about using tri-x ortho to make a man's complexion weathered or wet plate type emulsion to intensify the redness in someone's skin, or make someone's freckles pop out of their face when the both skins are smooth and clear?
The only truth of a photograph is that the photographer/camera was pointed at something, that's about it. Truth ( whatever that is ) is linked to the storytellers point of view. Regarding news outlets, they have a story to tell. It is not difficult to photograph a small group of people with a telephoto lens and make it look like a mob, news outlets are known to do that. There is a very famous movie taken in the 1920s or 1930s that shows a woman with a cellphone, and people who believe in time travel always point to that photograph to suggest she is from the past or future. Some argue that the device in her hand is not a cellphone but some other sort of device.
Me? I definitely think she is a time traveler on a cellphone ... its well known that they had wireless communication in Sumeria, Mesopotamia, and Babylon. It has been suggested that the hanging gardens were not gardens at all but 10G cellphone towers.
Art? Anything can be considered art, a banana duct taped to a wall, even images from Hank Hill's colonoscopy.
