I left some previous Scans - probably processed with Lightroom for comparison with current (2022) Topaz Denoise/Sharpen and Capture One 22.

There is some magic in reprocessing oldies with newer tools. But the JPG are not as amenable to 'fixing', compared to TIF (or RAW for the digital times).
The originals were on 'striated' matte paper, and required some processing at the canning time to remove the striations.
