As Jonathan Crary argues, "Vision is always an irreducible complex of elements beloning to the observer's body and data from the exterior world". This shows that vision is a complex process consisting of various elements and input from both observer and the object being observed. It connects the two into one process. 

    

Modern observer is not passive passer-by. According to Jonathan Crary an observer "posed a subject who was both the site and producer of sensation". This leads to the idea that in modernity there can't be objective, completely separated observer. Modern observer is always entangled and connected with what he is observing in some way or another, and ultimately becomes the sight of somebody else's observation as well.

Jonathan Crary states, "The perceiver here becomes neutral conduit, one kind of relay among others allowing optimum conditions of circulation and exchangeability, whether it be of commodities, energy, capital, images, or information." This implies that modern observer is just an element of much larger picture.
