That said, a jpg file is an 8 bit image. So, in most cases the conversion from a 12 bit or 14 bit raw file to the jpg will be visually indistinguishable. Depending on the raw coversion algorithm and the image, they may in fact be identical. However, if the image is processed they can be quite different. This is especially true if the post processing includes exposure adjustments, pulling back highlights or pulling up shadows.
