generate the tif files but, when viewd the resulting image on Windows, the image viewer shows foreground and background colors reversed. What might be wrong?

The Windows TIFF viewer you are using is likely ignoring the TIFF photometric. Perhaps it is assuming MINISWHITE but the file is using MINISBLACK. Your 8-bit grayscale TIFF image was likely using MINISBLACK.

I can verify that the issue described above by Bob is a known problem with Microsoft/Wang/Kodak Imaging, which is the default TIFF viewer that was supplied with Windows 98 and Windows 2000.
