I am trying to export from Lightroom to a JPG as an 8 bit file. Can someone explain how this is done? I don't see it in the export settings.
Jpgs can only be 8-bit, so you'll always get 8-bit when you export as jpg.
JPEG images are automatically exported with the bit depth of 8-bits, so there's nothing to choose. It's just part of the JPEG export.
Thanks to you both.
