My my, I certainly got somewhat of a rise with the whole 'sloppiness' point
I actually find nothing at all wrong with post-production via Photoshop or any other means -- for instance, there are times despite a bang-on exposure, attention to detail, etc., post-production is necessary to bring-out the best of an image. As we all know, there are times at the point of initial exposure that certain elements may be/are beyond our immediate control and compromises need to be made for any number of technically (and/or artistically) valid reasons. I am sure there are many of us here who at the time of exposure did so with certain post-production techniques in mind as part of their corresponding 'previsualization'.
For ex&le, back in the '80s I used masks, split-toning, hand-colouring and other post-exposure techniques extensively in my personal work -- I love Uelsmann's imagery but worked the techniques in my own way. Despite all this post-production work, its quality depended heavily on equally careful attention to choice of film stock, lighting, exposure, etc. for the stock negatives used within the composite images. More often than not, prints made from the stock negatives could have easily stood -- and often did -- on their own merit with little manipulation apart from light burning/dodging. The point here is that by being the foundation of a composite image, the stock negatives needed to be 'solid' or chances were the final image would not 'hang together' as seamlessly as desired. This is a quality that I often find lacking in many PS-created composites posted on forums such as photo.net, although outstanding ex&les do pop-up on occasion.
More often than not, what separates a person who approaches the medium with a high degree of professionalism from a hack (or one trick wonders) is a solid knowledge of the craft/art and its capabilities, and a corresponding personal ability to control the medium rather than be controlled by it. I shoot most of my personal colour work using transparency film in part because it is so relatively unforgiving, and the corresponding discipline translates quite well whenever I shoot digital
