My investigations revealed that neodymium doped glass absorbs wavelengths
such that the resulting composition of the spectrum is near natural
daylight. A visualization of the spectrum shows a gap where the absorbtion
occurs, and my own opinion is that a hole in the spectrum is likely to have
the same metamyrismic effects as a spectrum with spikes. Not exactly the
same, mind you ... but still not similar to a true broad spectrum as is
natural daylight. But then ... who uses daylight to evaluate their prints
anymore???
cheerios ... shAf :o)
