Can you tell me how to adjust in Lightroom the highlights amount, tone and radius? The same for shadows. I can see only 2 simple sliders in my LR for highlights and shadows. I would like to have same settings as in Photoshop Highlights/Shadows Smart Filter.
There are no Tone-Width and Radius parameters in the Camera Raw engine used in LR and PS/ACR.
In LR and ACR, Whites, Highlights, Exposure, Shadows, Blacks target different tonal ranges of values to some degree and what ranges they work with and how much overlap and interaction are pre-set but also dynamic based on the image data. It's not as simple as just the two tonal ranges of Highlights/Shadows adjusting inward from pure white and pure black in PS.
Besides there being 5 ranges instead of just two, the concept of white and black is also different because raw data has values beyond the white and black you can see on screen so there aren't even values like 0 for black and 255 for white that the extremity adjustments can be pinned to.
Basically the toning model is more complex in LR/ACR so the adjustments are fewer. In other words, the way toning works in LR/ACR doesn't lend itself to adding the adjustment parameters you're asking for.
It's always possible that Adobe will change things and create a completely new toning model that can be adjusted in the ways you're used to in PS, but so far, no.
