That’s a very broad request. I think the best info would be the following:
- The help text in the adjustment palettes (accessed by clicking on the ?).
- The technical articles at dxo.com under the Explore menu.
- Searching the knowledge base at support.dxo.com.
The history for these features goes back a very long way and largely predates the DxO forums that now exist. You could try to dig up release notes for the early versions of Optics Pro and FilmPack. I can tell you that ClearView Plus was introduced as an “improvement” in PhotoLab 2. I don’t think it was an improvement over the original ClearView, which goes back to OpticsPro 10 - but the rationale was to make the effect stronger while reducing unwanted artifacts. I think it’s usually much too strong. Smart Lighting changed a lot over time, sometimes not for the better - though I think it’s pretty good at this point. (OpticsPro 9 had a good formula that was retained for a little while and then disappeared in favor of a new direction that took several years to fully realize.)
Some people think OpticsPro 7 had the best formula for Smart Lighting.
