Rob, you seem to be arguing that "quoting" photographs, by presenting a thumbnail which can't be reproduced for commercial purposes, in order to refer to them in a discussion on a relevant topic, without the permission of the author, is inappropriate. I find this line of argument unconvincing. Your initial use of it in this thread, in order to counter a plausible suggestion that you simply hadn't read the OP with any care, was flimsy and your attempt to sustain it is even less convincing than that. I wonder if you would extend this to texts, or speeches, or paintings, or whether you would confine it to work produced by the living?
You seem to concede that that no law is breached but claim that some ethic of courtesy is, and you link this, with a rhetorical strategy you have used before, to your view that civilization is in decline, things ain't what they used to be, and so on. After the umpteenth time we have encountered this lamentation, we have to wonder if you aren't talking about yourself rather than the nature of things.
The quotation of images earlier on this thread involved no plagiarism and no disrespect to the photographer - quite the opposite, the photographer was "quoted" in order to be praised for the appropriate use of a stylistic device. The "fair use" concept (which isn't merely legal, it shows the law shaped by fairness and common sense) applies, because the "quotation" advanced the discussion by providing a clear explanation of the kind of thing the poster was talking about, and there is no collateral damage.
On "barely color", I am deeply curious about, because I don't at all share, the viewpoint of those who object to it as necessarily excessive, artificial, gimmicky etc. It seems to me just another technique, like dodging and burning, a way of shaping the experience of the viewer. There seems to be a view in play as to what is and isn't acceptable in "photographs", some line not to be crossed, that I don't get. To me, photographs are another kind of painting and you can make choices about colors either before you press the button, or after. Lula does seem to be largely a temple in the religion of those who don't think like this, which makes it an interesting place to hang out for someone who does.
