I think the actual article under discussion has one hugely valid guy to ignore: Henri Cartier-Bresson and his "decisive moment" theory, and his extreme ONE-LENS mentality...he used the same focal length for almost 99% of his images, for his entire career. Yes, the same focal length, over and over and over and over, for thousands of images. Boring as hell. Visually stultifying. He was a street shooter, by there were other shooters equally as talented, and IMHO, even more talented. People like Alfred Eisenstaedt for example.

As Formhals says in his text, before HCB came along, street photography was wide-open and had a lot of different types of photography in the genre, but HCB's vast popularity has caused many newcomers to emulate the man's narrow,restrictive, rather predictable style. Imagine a guy who touts using a 50mm lens for 99% of all images made over four decades...that's hegemony...it's also a lot easier to mentally frame an image when the field of view and the fore/back-ground relationships are as dull and boring as they are from a 50mm lens...
Some of the other "street" shooters that came before HCB created work that was more-compelling, more-varied, and flat out "better", in my opinion. Pick up the new HCB book Portraits, and look at how very average the man was as a portrait shooter. What HCB established was a concept of one specific moment being better than any other, and also, basically the idea that one would skulk around with a 50mm lens and wait for people to make a shot interesting by virtue of shooting at weird times...contrast his work with that of say, Brassai

and the reasons Formhals admonishes people NOT to emulate HCB become pretty obvious. It is not that these old, mostly dead masters are bad artists, but their life and times,and their type of work, are simply not possible to re-create,and frankly, who would want to become just a re-hash of somebody else???
