I am developing some s/w to create grayscale images from a datafile. The code originally generated JPEG files and I am transitioning to TIFF files. My TIFF files are coming out with the grayscale spectrum reversed from the JPEG files. Obviously, I can reverse the spectrum in my code but I was wondering if there was a more elegant way to do this such as TIFF tag settings to specify which end of the spectrum is white and which is black. Any suggestions?

Thanks,
Bob
