It's hard to pick one representative example, but the whole channel is a better example than the video linked in this HN post. Where this video says things such as "using precision tools and carefully selected materials", Baumgartner walks you through what tools, what materials, and how/why he decides to use those materials in a way this video does not.

I'm supposed to be finishing up a changelog entry for a software release, but this is fascinating. Watching someone execute their craft at this level is mesmerizing.

You did warn us though.

Was just about to recommend that same channel. In comparison to the article video, I find Baumgartners style much more educating and soothing. Though the process they use for restoring paintings seems pretty similar, it's always interesting to see new ways of doing things.

Lots of details irked me, that was the biggest.

The most evident part was where they showed a close-up of the new canvas, and the corner cuts did not line up.
