8-bit vs 16-bit Pakon comparison

Each pair below shows the same scan: a standard export from TLXClientDemo with all default settings, and the result of PPRC being run on 16-bit raw exports. All images are Portra 160, and the PPRC ones have been converted from AdobeRGB to sRGB.

Every image displayed was given the same one-click "Auto" adjustment in Lightroom Classic. This comparison shows how the scans respond when you start working on them.
