RE: wondering

And many lenses, even very good ones, have diffraction fringing at small
apertures. I'm starting pinhole photography specifically for the look
and feel of diffraction for certain images I have in my head and want to
create on film. It's only a flaw if unintended and ineffective.

Or if it LOOKS unintended and ineffective. (Hey, I'll take a lucky
accident as readily as the next guy...but as someone once said, the
harder I work, the luckier I get.)

After much digital labor, I don't believe that it can be done digitally
as well as in creation of a first generation image.

Also agree totally with the assertion that lack of sharpness may be due
to imprecise matching of pinhole focal length and pinhole to film
distance. The proliferation of commercial pinhole cameras is what
convinced me of this. There seems to be a pretty consistent look to
images produced by any one person's branded pinhole camera, but others
get different amounts of sharpness in the images they produce using the
same make (and theoretically, specification) camera and pinhole. Again,
well known in lens world, "normal" manufacturing variability is by
definition bounded by abnormal and therefore unacceptable results.

It occurs to me that lack of sharpness in pinhole images is not inherent
to
the nature of diffraction photography. It is caused by lack of precision
in
matching the diameter of the pinhole to the distance to the film, or in
less
than perfect pinholes. Thus it could be said to be a lovable blemish
attributable to the operator rather than an essential characteristic of
the
process to be defended against heresy. Or something like that.
