Absorbance, transmittance and reflectance all different types of spectroscopy. What I want to try and do is be able to acquire a visible spectra of something using a camera. Decomposing RGB values into a spectra is going to be tough but I think if I base it on empirical values from a spectrophotometer. Wavelength might not be too crazy but intensity is going to be the tough part. Was working on using a webcam today. I think I need something with a little better resolution.
