Hi Tommy,

Photoshop 5.0 LE (comes with Canon's software CD) will allow you to import 42 and 48 bit color files. You need to click OK or whatever it offers to allow the scanner to continue. I remember this from when I first used my FS4000US. The scan will then be imported (listed) in Photoshop as a 48 bit (16 bit/channel) file. I prefer to leave it in this mode but it does restrict the filters, etc. that can be used. If you need to use more filters, simply click on Image, then Mode, then 8 bit/channel in the Title Bar and it will be converted to a 24 bit file.
