16 bit Tiff

Miscellaneous Forums/General Discussion/16 bit Tiff

Hi there,
I'm working with photos in 16 bit tiff format but I'm trying to use the modification algorithm from HP which only saves them in 8 bit tiff. If I then put them back into PSP I can increase the colour depth back to 16 bit but will it be genuine or will I have lost the true quality from the original 16 bit?
Thanks in advance.
Regards
