Seeing a spectrum is one thing. Reading-interpriting one is another. I know from first hand experience that one can get so caught up in analysis that you frind yourself doing nothing but analysis. An organized multi-person effort is about the only way to go here. I have known photographers who do nothing but curves on graph paper. Thats fine. It obviously makes them happy. So, I let you make the spectrometer. Then I will send you samples to read!
