This has nothing to do with ethics and everything to do artistic and aesthetic decisions. From an artistic standpoint, I find a lot of over-photoshopped work to be pure kitsch--sentimental overwrought, and artificial. I accept the fact that this sort of "artistic power" has never been available to those without traditional illustration skills, so we're seeing a lot of overindulgence. I think widespread digital overmanipulation has been driving a good number of people back into traditional and alternative photographic processes--which seem to be thriving these days. As to the "value" of digital art--the cow is already out of the barn. I find most buyers are interested in the artistic vision and less so in the process and materials--unless we're talking about process art, which is still driven by the artist. Is the trend more toxic than the excesses of pictorialism or the dullest incarnations of the latest new topographics? Probably not.
