LIGHTROOM: Allow 8 or 16 Bit Conversion in all "Export/File Settings" options, not just in PSD

Please allow Bit Conversions - 8 or 16 with any and all options in the File Settings part of the "Export" process. Right now in LR5.4, I can choose 8 or 16 Bit but ONLY when making a PSD. I want that option when making ANY file type.Having to use an external editor just to convert at the end of processing unnecessarily adds to the workflow. Thank you in advance for your consideration of this improvement to LR.

Certain File Types do not allow certain bit Depths.

PSD and Tiff both already allow 8 or 16.
JPEG allows only 8.
Original only allows saving as Original (this will never change)

It is the file specifications that demand this - not Lightroom.

You will need to explain better just exactly what you are trying to do here.

OK Master Rikk - I have DNG & TIFF files that I need to export in 8-Bit (and convert to JPG in the process). There is nothing that I have read in any LR related blog/forum etc that guarantees me that by selecting "Export/File Settings/Image Format" and choosing JPG that the file will be converted to 8-Bit. It has never been an "assumption" that wherever I choose JPG that I also end up with 8 Bit.

If a LR JPG selection automatically is converted to 8-Bit Depth "behind the scenes" then i have learned something else today. One less step in my workflow. Thank you.

The JPEG File Format spec does not allow for saving in anything other than 8 bit. It is part of the file spec. Lightroom must comply with this specification or no other program will read the image exported.

Anytime you hit Export and choose JPEG, Lightroom renders an 8 Bit file.

It is like that for all programs. Some programs just aren't smart enough to do it for you and require you to down-sample bits prior to saving to a lower bit-depth.

Thank you, Rikk. This is a wonderful 'confirmation'; all I needed to hear and one less step in my workflow - attained.

Than you.
