Lee Tarpley sent an email on 12/7/00 2:41 pm and had this to say:
>You'll see the various spectral ranges of the films, regular film records
>light up to about 680nm, extended red films go up to about 720nm whereas
>infrared films cover the range up to 900nm, the infrared spectrum kicks in
>about 700nm, A WAVELENGTH BELOW WHAT THE HUMAN EYE CAN SEE, this is where
>things start to become interesting!"
>
>This phrase is confusing, and I'm guessing is the source of the e-mail
>discussing frequency. The 700 nm is near (or barely within?) the cutoff of

>700 nm cannot be seen by the human eye. This region of the spectrum is where
>things start to become interesting!"
I modified it this morning to what you've quoted, the original was "above
what the human eye can see", clearly taking into consideration frequency
(which isn't mentioned on my website, only wavelength) I modified the
wording to reflect the changed opinion.
I like what you've suggested, so I'll replace it!

I play the harmonica. The only way I can play is
if I get my car going really fast, and stick it
out the window. I've been arrested three times
for practicing.
I put a new engine in my car, but forgot to take
the old one out. Now my car goes 500 miles per
hour. The harmonica sounds *amazing*.
