More bokeh from the Film Era, when hardly anyone knew it was there or at least they never mentioned it by that name. SCANS

Started getting involved in photography in 1969. Never even heard the term until I joined this forum in 2013. My first reaction to the word was "What the heck is bokeh!"

Precisely. FYI in case you did not know, SFAIK it is a word imported to English from Japanese at least some of whom were concerned with the artistic rendering of backgrounds in photographic images.

A word that was popular for evaluating lens quality when I started in photography was "acutance," which seems to have been replaced by something like "micro contrast" even though acutance has an unambiguous definition that includes an objectively measurable property in a photographic image.

From Wikipedia (bold print my addition): In photography, the term "acutance" describes a subjective perception of sharpness that is related to the edge contrast of an image. Acutance is related to the amplitude of the derivative of brightness with respect to space. Due to the nature of the human visual system, an image with higher acutance appears sharper even though an increase in acutance does not increase real resolution.

I have purchased and been using a Topaz add-on called "Sharpen AI." It offers three "modes" to increase sharpness 1) sharpen; 2) stabilize; and 3) focus. Of these, by far the best is stabilize. It basically increases acutance by making the edge between one tone or color and an adjacent tone/color that is substantially different essentially shorter or more abrupt, rather than being slightly feathered. There is no increase in detail (= resolution), but the psychological perception of sharpness is greatly enhanced.

K-1 with Leica 35-70mm Vario-Elmar-R f 4.0.

Seed pods, on a cold sunny day.

SMC-K 28mm f3.5

I'm not sure what type of plant this is, but it never lost all of it's leaves. These just turned a maroon color, and never left the stick.

It seems to be growing still with the temps below freezing.

My second attempt at trying to find a use for the 20-40 Limited (on my KP). Dew on a thin strip of moss in a crack in some concrete.

Frost evading the bokeh, a variation on an image posted earlier. SCAN
