A Study in Pseudogrammy-
This is a SuDagraphic portrait of myself.
A SuDagraph is a variety of Pseudogram, which is defined as a single image PHOTOGRAPHIC auto-stereogram. Although Pseudograms existed for some time in Stereoscopy’s short but robust history, they were overlooked as being “accidental” or “found” stereograms and no one had ever researched them, classified or defined them for 180+ years..
This is a format I’m credited with discovering, defining and naming. They have 4 years of research behind them, have been presented at SD&A, respected stereographer David Kuntz watched by my side during my whole process & were confirmed by dozens of upper echelon illuminates of stereo history and research.
I named them Pseudograms because the category of auto-stereograms which have been classified & defined are almost exclusively computer generated images and until very recently (the past 4 or 5 years or so) were 99.9% orthoscopic as PARALLEL VIEWS ONLY.
Pseudograms are ALWAYS ONLY SINGLE IMAGE PHOTOGRAPHS, and except for color correction, cropping and rotating- must remain otherwise unaltered to be defined as such.
Pseudograms also produce orthoscopic views when CROSS VIEWED, either by free viewing or with the aid of a Pseudoscope.
A SuDagraph is an INTENTIONAL variety of PSEUDOGRAM. Since they exist accidentally, I had to give careful consideration as to what the delineating factor between found and intentional stereoscopic imagery might be, and thusly discovered it is this act of artist intent, which defined is as an intentional format.
Much to my surprise (and everyone else’s as well), I was it’s first real practitioner.
I named this artist intentional variety of Pseudogram a SuDagraph in honor of Susan Pinsky and David Starkman borrowing the Su and Da from their first names, as it is pronounced similarly to Pseudo.
By nature, Pseudograms will contain rivalrous elements, which are tolerable by most stereo-viewers.
The study of WHAT visual elements an image contains that allows for fusion (vergence/accommodation) in the face of such stereoscopic rivalry & WHY, is something I study heavily.
I will be posting more about Pseudograms and SuDagraphs in an upcoming long read article.
