While surfing I found a site which sells spectrophotometer kits out of paper and cut dvd for iphone or video cassette case, cut dvd and webcam.
9 Dollars for kit and 10 dollar for postage , I will find a phone and go from there. I have lots of friends and one of them should have it.
I found national geographic rotogravure tiffdruck prints are amazing 85-95 time scale and I will analysis a 1989 issue and report here.

Problem , how would be the light source glowing on paper been selected ? Mid sunny day , bulb light , fluorescence light , studio light ? Do light source changes every detail or would spectrum results not change ?

I will report everything at articles .
