How to "scan for shadow details"? To achieve Jose Villa kind of look

Hello,

I am interested in getting a light and airy film scan. i.e. this look :

Richard Photo Lab made a post explaining that you must “scan for shadow details”. (https://www.richardphotolab.com/blog/post/how-get-light-airy-film-scans)

I got one roll of overexposed film (1 stop over) and tried to scan it but result came pretty normal. I tried to overexpose my DSLR camera by a stop too (Exposing to the right a bit more than usual) and just got contrastier scans.

This post explain a bit more in detail what is the Richard Photo Lab’s process : http://www.johnnypatience.com/richard-photo-lab/

What would be you advice on achieving this style with NLP and Fuji Pro 400h?

Thank you.
