Hello, We may interact with any live person by its emitted, transmited, reflected spectrum or otherwise and get effects? We can't think about emission and transmission of emited radiations in consideration to this topic subject. So we now left about reflected spectrum--shape. colours etc. So; Can a photo of somewhat true colour and spectrum effect us alike a live person? We may get some psychlogical emotional effects but these are also "getting effect" by looking and recognizing a photo. We also interact and get effects by interacting with "Black & White" photo. Similarily, we can also think about, origional/live structures for their effects by reflection spectrum. So pls guide me accordingly. Best wishes.
