scanning – Correct exposure negative scan

I’ve just started scanning my families negatives. When I get the scan, it’s a bit brighter than the print that was made that I can compare it to, but the print has less details in the dark areas.

Alas, if I bring down the exposure in post, I get an image more in line with the print, but instead those before mentioned shadows swallow some detail. Is there a right way do do it. Which is the “true” image?
