*For those using unmodified cameras: You may still reveal parts of red spectrum
without any modification if you search for the red violet instead of the 659 nm line. 
The camera is still sensitive to the shorter red line.  Work Curves very
carefully, never clip the histogram, and you will be rewarded.
