"Mossy path" - revisited by monocular stereoscopy
The first displayed image is one from a stereoscopic pair published by stubeans a few hours before this post..
The second image is a side-by-side stereo pair derived from the single image by using the 3D_SBS python tool in a ComfyUI workflow (all the software open-source and freely available for use offline).
The point of this exercise is to demonstrate that an ordinary 2D photograph of a 3D scene contains the necessary information for the brain to construct a 3D view. The ocular cortex of the brain is given the necessary prompting by the results of an image depth/perspective analysis being separated into the necessary two images.
There will be subtle differences between viewing the true stereo pair and the ersatz pair. In this instance they seem to be absent or minor. Sometimes, calculations leading to a constructed stereo pair go a little astray and anomalies will be visible when the combined image is perused in the brain.
The construction algorithm has several parameters enabling tweaking the result to alter the impressions of depth and focus.
Whilst dual lens recording equipment can give optimum results, the enhancement of images taken using lesser apparatus should not be gainsaid. Moreover, 2D pictures of scenes made by artists take on new interest when rendered into 3D; arguably they more closely represent what the artist had in mind, but could not fully realise because of the nature of the medium. Enhancements of this nature don't replace the original constructions, yet they might attune the minds of the artists and the viewers of their works more closely.
I intend to present examples of paintings and drawings revisited in stereoscopy.
