In the days of the internet age where it seems almost everything is posted unfiltered to flikr or other photo sharing sites he probably would have struggled to make headway against the constant flood of images. Today you need to be putting stuff out constantly, or you need something completely novel to make an impact, no time for reflection and nazal gazing and definitely no time for the pursuit of pure excellence of execution within a specific photographic discipline.
Truthfully such arguments are probably code for, "I don't have the ability or patience" or "I have no idea what you are doing".
Regardless however, these arguments miss the point, artisans don’t spend inordinate time fine tuning the little subtleties of an image that most people miss because they want to please the great unwashed. Artisans go the extra distance so they are fully, truly satisfied with the final result in their own heart and soul, they work to a higher standard and expect more of themselves and their images. That the average snapshooter, peripheral photo dabbler or photo forum lurker fails to realize this is totally irrelevant to them.
The net of course works somewhat contrary to the higher pursuits in photographic quality because the demands of a small web image are quite different to a large scale fine art print, a fact lost on most casual observers of on-line photography. Yes I know that most photography these days is consumed as 1000 pixels wide on a low grade monitor, so what, most photography in the past was consumed as poor quality slides or grainy fuzzy postcard prints, that doesn't mean we should judge photography quality by such a low standard. Regardless of technological changes, a high quality good sized print is still the gold standard, a great print is what will sort the artisans from the tinkerers, or the truly serious from the mildly dedicated.
But the editing and printing are not the only factors that artisans use to judge their work, it goes back, way back to the shooting and pre-shooting phases.
The may, plan the shoot for days or months or even perhaps years. A lot of people poo poo Adams' ideas of pre-visualisation these days, but perhaps that is just because they have no vision themselves. All of the really good photographers I have known definitely worked to a personal vision, all took the art seriously and were prepared to put themselves out to get the results.
They all had something else too....persistence!
I guess this is the message I want to leave you with, be prepared to slow down and perhaps take less images with greater intent, concentrate more, edit less photos but at a deeper level, become more self critical and chances are you will see a greater improvement in your photography.
And if you do stuff up, well accept it as a success, cause it is one more thing you will know not to do in future, and in any case who knows what you might learn from those mistakes.
