RE: filmscanners: What's MFT

[Frank Parrotta <fparrotta@tscwo.com>]

John,

Are you sure it wasn't MTF which is modulation transfer function.  MTF
describes the resolution of an imaging system.  It is the response of the
system to different spatial frequencies (usually expressed in lines per
millimeter) and is typically presented as a plot of some output parameter
(e.g., intensity, voltage, etc.) for some element of the system (lens, film,
or the whole system) as a function of a square wave input signal.  If it was
MTF, then my guess is that the adjustment they were referring to was
probably to the electronics used to amplify the signal out of the CCD.  Hope
this helps.

BTW, I have a SS4000 too.  Fortunately, I bought it from a reputable dealer.
The first unit was DOA so they replaced it out of their stock.  The unit I
have now has provided excellent service.

Frank
