Ok ok. I was thinking that it should be more contrasty because my enlargements are but then actually I dial in a whack of magenta(?) filter in my enlarger.
Edit: your version looks a lot better. More farting around in Lightroom then.
If you do enlargements the paper adds the contrast. I would recommend to save the file as
a 16bit Tif in Lightroom and do the rest in Photoshop. Lightroom doesn't know you
work on a negative and a lot of settings will be backward and not work properly.
A negative just reversed should look flat, it's a log image. At a minimum you need to set you
black and white points and apply a s-curve.
