AI drop shadow

[jewelb39990263]

An Adobe support person helped me remove the background from subject. Along the way and last couple of steps he utilized AI and went to invert subject. I lost next steps but as a result he created automatically a shadow around the subject that turned out quite nice. Can anyone help with those last steps?

Perhaps a layer style?

Can you elaborate?

The transparency was created using Select > Select Subject perhaps with a layer mask, or perhaps using the "Remove Background" command etc. These are AI-trained selections (Adobe Sensei).

I'm not aware of an "AI" drop shadow though, I am guessing that a Layer > Layer Style menu command was applied to the layer's transparency:

Probably using Drop Shadow, and or perhaps adding Outer Glow using black and multiply blend mode as well.
