[filmscanners] Re: Digital ICE

Jack,

Thanks for that explanation of Digital ICE. I have a LS4000 which I use with
NikonScan 3.1 and also have Vuescan. Does Vuescan use your Digital ICE
technology in exactly the same way as NikonScan, or has Ed Hamrick had to
write different software to try and achieve the same effect?

The film version of Digital ICE never "replaces" pixels damaged by surface
defects. That is how some of the other versions of infra red surface defect
software work. There are several programs out there that use infra red to
identify surface defects. Digital ICE is unique (and patent protected) in
that it "looks through" the surface defects and identifies the underlying
information in the film. That is why Digital ICE doesn't work when there is
a hole in the negative. If you take a pin and punch a hole in a negative or
scratch deeply into the emulation of the film, the defect will be identified
but not repaired properly.

..........

I hope that answers your questions! Feel free to email me directly if you
have questions the group as a whole may not be interested in hearing about.

Good luck with your scanning!
