semilog
curmudgeonly optimist
I suppose what I would have been claiming, if I had been claiming more than I wrote, is that there are limitations to a backward-looking, counting-based approach to aesthetics, and that some of those limitations are on display in this thread.
My view of this is that if you know the history of photography, you know that there is very little under the sun that is new. Probably the only thing really new in the last two decades, in fact, is the advent of low-noise, high-ISO digital sensors. But these have little effect on DoF (the subject under discussion), as such.**
With respect to DoF, we may in fact conclude that (in a technical sense) nearly everything worth trying has been tried, many times, by many people. That is, a large parameter space has been well-sampled by good photographers. So we look at the products of this intensive sampling, at what has emerged as the most important work in the medium.
My contention is that shallow DoF is not a technique used in most great (long-lasting, influential) photos. Some, but not most.
**I've just realized that the elephants in the room, the things that are dominating today's photographic DoF vernacular, are not Noct-Nikkors and Summiluxes – but rather the Holga and the Lensbaby.
