My setting to use something different than a dedicated film negative scanner. I used as shown a trip, my Nikon D800 and a light table.
After photographing the images I import them into Lightroom where I made a preset for an inverted curve. The only thing to be aware of is that all sliders are moving mirrored to the normal adjustments. I just had as a trial the HP ISO 400 film taken with Leica M2 and 40sm lens at f8 zone focusing.
