Right. Use the filter as the last step in your post-processing.

Is that colour or optical filters.? I learned at a Photoshop course, that there are a number of ways doing things in 'Photoshop' to achieve the same end result. Perhaps keeping 16 bits in use , and using colour balance, to get the colour filter effect not available (Greyed-out). Will have a look myself , when I use Photoshop next time. Learning all the time.

Thanks to all who contributed to this thread. Out of 1163 'Views', just 9 people who added to the original post. Does that mean that the other 1154 'viewers' know / knew all about the differences between using / keeping / saving 8 or 16 bit files. Or were not really bothered after all. I learned things I did not know, so am grateful to those who took the time to add their bits of information. I think the thread went well. No 'Name Calling' insults thrown around. Well done all.

Oh please don't complain about people who viewed but didn't response. Lot of time you're not sure, you don't know the answer, so you don't answer. That is actually a nice and right thing to do.

Image quality is a function of data contained in the image file. While the human eye only needs a certain degree of data, normally that contained in an 8-bit image file, to see a file and consider it as a quality file there is the issue of processing to be considered. The most important aspect of our image files is the tonal range contained within them. A 16-bit file has a much wider tonal range than an 8-bit file and thus we can do more processing of a 16-bit file without creating tonal range artifacts within them that might affect the quality of our image. Photographic files are referred to as "continuous tone" images so the more tones in an image the more likely we are to have good data to work with in the image and the less likely the individual tones will show as we process the image, thus we have a smooth gradation from tone to tone. This is the reason that it is best to keep the original file size of 16-bits, which contained the most tones for that image.

Most likely place to see a difference is in the sky where the tonality changes from dark to lighter. Sometimes with 8 bits you will see the sky broken into somewhat jagged horizontal bands rather a smooth progression of tonality. 16 bits will prevent this

Please don't think I was complaining (Heaven forbid!) I just thought there were a disproportionate number (now 1996) of viewers, to those who had something to add. So ...thankyou to all of the viewers who did not add any comments. Have a nice day.
