[filmscanners] how to scan 'red' 'green' or 'blue' lights?

["Dieder Bylsma" <scanners@spacemoo.com>]

I've noticed something over the past while when scanning pictures
that have 'stop' lights or green 'go' lights in them. The result from
scanning usually ends up in an strange 'hot' red, green, or blue
result that looks a bit bizarre.

i.e. a picture of a car with its brake lights on in the middle of the
day. The result is an unusually 'bright' red result on film that does
not appear in the print, but does appear in the scan.

Is this just a function of the LED light source of the LS-4000, or is
this a function of RGB sensitivity by the CCD sensor?

thx for any insight,


Dieder
