Program
How does a black-and-white camera make color pictures? What is ΔE and why is it important? How do camera sensors work? What is the Stokes Shift and why is it essential to the recovery of texts? What is the relationship between wavelength and ink visibility? How do apochromatic lenses improve sharpness in the UV and IR? Why does spectral resolution come at the cost of spatial resolution and vice versa? Designed for humanists, this lecture lays out the science of spectral imaging in clear and accessible terms and answers the questions you did not know to ask.
