1. markjwyatt refers to the concept that photography is an act of taking rather than of synthesis. As a result "When a viewer experiences a photograph, it is presumed (maybe less so today) that the scene is an actual one, and the emotions/ideas/etc. have a firmer grip in reality, and thus can actually have more impact than a fanciful painting. Because this is a scene from real life."
This relates to the commonly held view of the specificity of chemical photography; that the light that has passed through the lens has marked the light sensitive medium in a one and only way. While the route to a digital print requires a human built algorithm, it is only a slight stretch to include this as being quite direct in the relationship of light reflected by the subject and the result of the light sensitive medium. Just today though I was reading of "Night Mode" and "Portrait" computational bokeh and other in camera computation changes that draw digital photography away from the one to one concept.
2. Alan Edward Klein remarks in the memorial nature of photography, which I think speaks to two things. firstly that a photograph, once taken, is instantly of the past and considered to be a accurate token of that past. As such it can be a believable standin for a valued but temporary experience of event perhaps involving an important person.
3. Vaughn suggests the ease of use is important. and asks
"Cowanw...What do you believe to be the underlying foundation aesthetic (characteristics) that photography is best at or that best represents photography as distinct from all other forms of graphic art? And why?"
Post 238 answers the first part of this.
I think that photography has a capture nature of direct relationship to the reflected light,in general, more than other mediums.
This is the main point featured in markjwyatt's and Alan Edward Klein's posts. It has been generally believed that the directness of the light reflecting off the subject acts on the light sensitive medium in only one way. This ignores the fact that a scene is composed that the scene can be changed that filters may be used or the reflected light may be altered in any way before it passes through the lens. Even after the lens, for the pendant that points out a fly in the bellows can have an effect. but the light hits the medium and causes changes that are predetermined to have an effect. Yes it can be manipulated chemically or digitally but in its most straight forward form it is consistent and predictable
I think It can stop motion as well as synthesize light over long periods of time.
Vaughn says "It is not stopping time or showing long periods of time. Painting and drawing can also express that...especially since seeing photographically is common now." I would suggest that the effect of a time exposure on the image is direct and consistent as opposed to "expressed"
It has a consistency and is generally repeatable in its negative or digital storage iteration.
Vaughn points out The Graphic Arts is filled with printing processes." Well that's true but the printing processes that do not involve photographing or scanning something and digitally printing are still magnitudes harder and more unavailable than the millions screens displaying photographs, the millions of inject printers printing photographs, and the thousand of darkrooms printing photographs. Ease of reproduce-ability is the point here, for me.
It can be simpler and more egalitarian at least more so than mediums like painting or carving.
Vaughn seems to agree with ease of function, at least in part.
But yes Faberryman's wit carries the day. Mostly nobody has read the book, eh!
