that article is quite bastardized >x>;;;; the timing is off, the way that he created the work is incorrect and the only traced photos he did of the tomato cans came long after the works shown in that image. those were created by silkscreens and stencils, here is the image he copied for that installment;
upload.wikimedia.org/wikipedia… your theory is unfounded and lacks any actual evidence. claiming that a large cultural shift in perceived beauty and socially desired works can be chalked down to several hundreds of thousands of people getting hold of a device that would be very costly and difficult to make and taking up tracing en mass but not having any written documentation of the use of this device or having physical evidence of the device in whole or part in said works or locations is ridiculous, it also discounts on face the world trends of the time both before, during and after the art renaissance as well as centuries of clear physical evidence showing the movement away from strongly stylized art to strongly realistic art
this is nonsensical and you have done nothing other than prove that you know nothing about the history of art or math or cameras
