Shroud Solo Show ( Part 11) Sunlight Based Hypotheses ( Proto Photo, Shadow Solar Reflex Models)

In Part 11, I continue my analysis of the various Ordinary Artistic imageforming mechanisms, hypotheses, specifically focusing on hypotheses based on the invovlement of sunlight as the imageencoding mechanism. There are three fundamental types of such hypotheses; i) The Medieval ProtoPhotograph (ProtoPhoto) models (Piknett Prince and Nicholas Allen), ii) Nathan D. Wilson s Shadow model and finally, iii) Serge N. Mouraviev s Solar Reflex model. RSM Blog (with various free scholarly sources and my 300page Shroud chapter writeup materials)
