A Process Method to Develop Photographic Images from Etched Stones

Photographic Developments From Petro Photoglyphs:

A Process Method to Record Images from Stones with Embedded Photographs:

In order to view the reflections from specific artifacts scribed with photographic surface images,

a method was developed to define, record and translate the glyphic structures

using a variable combination of the following factors:

1. Spectrum Filtration: and the selective illumination level of the image. The control of the image illumination wavelength and amplitude.

I.E. The development of an inverse or photo negative, or a red enhanced image.

2. Dimensional Perspective: or the position of the artifact with respect to the viewers’ source.

The source could be a camera or other visual recording device. The objective focal and angular position would be the variables.

3. Bilateral Symmetry: applied to mirror a portion of the source glyphic structure and provide a foldout or ‘butterfly’ of the information.

The bilateral line would typically intersect the glyphic image in a vertical or horizontal plane and will orthographically shift the image position.

This process method for image recording can also be applied to conventional rock art and its interpretation:

A development of the glyphic image structure incorporating two of the proposed factors in the process method for recording rock art:

spectrum filtration and bilateral symmetry.

The dimensional perspective and focal point remained constant in this sample translation.

Applying the defined process method to 'petro photoglyphic artifacts' develops the embedded image structure

provided by the artisan.

The communication is then transmitted with the visual detail necessary to decipher the recording.

The message can now be understood, as intended by the artisan:
