Scans are corrupted

[mactonio]

Hi,I just installed Silverfast (8.0.1 r18 on Mac OS 10.12.4) with a Plustek 8200i scanner.
I think the scanner is ok, as for the preview image you can check here.

But when I save the file, regardless its resolution or file format (both JPG and TIFF),
I get a corrupted (?) file.

What is the problem?

Thanks, Antonio.

Dear Antonio,

B&W film unfortunately can not be corrected using the scanner's infrared because the silver halide wmulsion blocks infrared light.
Please deactivate iSRD. You can use SRDx instead.

Kind regards,
Arne
