Blacksmithing usually happens in a dark shop with very hot metal. A dark shop helps the blacksmith see the color of the steel better and thus know when it's ready to work or when it is too cold. Unfortunately, the dynamic range between dark and light makes it difficult to create videos that show both the shop as well as the hot metal. The dynamic range is too high to show up appropriately in videos. Fortunately, this has changed with Youtube's support for HDR. It still requires a new TV to support it though. This video is my first experiment at producing an HDR video. I filmed it on a Sony PXW‑FS7 in 4K raw and then color graded it in DaVinci Resolve on a Sony BVM-X300.
The Mysterybox folks have put together good information on how to produce HDR videos.
