[photo-3d] RE: misconception of matching photoshop colours

Andrew,

Thanks for this informative post.  I have often wanted to know the
spectrum
from a CRT.  Do you happen to know how variable the spectra of CRT's
are?  Also, would you be willing to share the raw data, for example
as a text file?  Thanks!
