Personally, I was astonished that anyone could react as Ray did to Kevin's pictures (except, perhaps, for the degree of processing in some cases).
I am astonished that you are astonished, Eric.
So far, from the comments in this thread, I'm getting the impression that many of those who like Kevin's image, Heavy Metal, do so because they have some past, pleasant association with heavy, industrialized equipment, and have perhaps once worked, or continue to work, in a comfortable office in a water-works complex, nuclear reactor, or other environment with heavy machinery.
That's fair enough. I'm criticising the photo, not people's opinions of it. Photos usually bring to mind certain associations and feelings in the viewer. If a photo doesn't do that, then an appropriate comment might be, "It doesn't do anything for me. Can't see the point", or something like that.
We must all have witnessed the great significance that some people attach to what appears to be a very ordinary snapshot. The reason is because the snapshot invokes certain memories in the owner, which might not be depicted in the photo.
For me, the associations that Heavy Metal invoke are of a Dickensian, child slavery environment, an ear-damaging, constant clatter of machinery, and a drab, mind-numbing decor.
However, I would concede that in the category of the Grotesque, Kevin's image does have some merit.
As regards your image, Eric, at least it does depict a rather pleasant, rainbow-like arch.
