Photography is not any different than any other artistic medium, yes I concur, it is wildly subjective --- as is film, painting, writing, set design, choreography, music-- it's all a matter of interpretation. Different interpretation isn't always a bad thing...
for example:
Fosse = slow comfortable screw; versus Marshall =one night bump and grind. Both have merit, neither one unanimously loved both never to be viewed as one in the same.
What a photographer chooses to frame within the window, may in fact hide some things, but it can also expose others.....and while it may fracture or reflect light to enhance or limit a scene, in my opinion it is no less valuable than any other artists rendering.
The problem, as I see it, is that people often see one image (picture) and then perceive or believe it to be news (reality).
