Minor White taught that abstract photographs blur the line of communication from photographer's intent to what the viewer sees.
So I would think "intent" is irrelevant for abstracts. You put it out there and the viewer tells you what they see.

I'd like to read something by Minor White or his direct students on this matter. I'm familiar with many of his and their prints and recognize that Photrio denizens might label some as "abstract" ..however I think those examples (e.g. famous ice crystals on glass) all (maybe) refer directly to physical phenomena the highly skilled photographer and observant person both recognize in the world, without being photographed (e.g. ice on glass). I don't know of examples that are mere phototech muddles.
