by FAU lamp is stored in “Color24_0.tif” file, and the image scanned by IR LED is
stored in “IR_0.tif” file. Both files are included in the folder of the Canon Scanner
Test.
IR.tif is an infrared image scanned with FARE function working. If FARE function
works normally, only dirt or dust on the film will be scanned as an image. If FARE
function does not work well, IR.tif image will be all in black.
When scan count is set at 2 or larger number, the scanned images are saved in
more than one file including Color24_0.tif/IR_0.tif, Color24_1. and tif/IR_1.tif.
Note: When scanning a film, the color of the scanned image may appear lighter than
that of the original film. This is because the image is not subject to the image
processing yet.
