Progress with RT 5.9 Film Negative

Hi!

In the white balance module: I read in another article about the film negative module that I should use the selection of the light source (where the film doesn’t cover) as the neutral point. Is that correct?

Yes, it is correct. Please keep in mind that the white area where you pick your WB spot should not be near clipping. So, it could be a good idea to take a separate shot of the backlight only (without the negative), with a lower exposure.
You can then use the same WB values for all negatives “scanned” with the same backlight and digital camera.

Regarding the strategy for selecting neutral points in the film negative module: one should choose a point with the highest density (such as overexposed areas or spots in the image). What about the other point? I see in the images, it’s selected from black objects in the shadows (now totally underexposed black , right?).

Ideally, you would not pick a spot with the highest density, but rather a spot that was white in the original scene. And another spot that was black.
Or, more generally, two spots that were two different levels of gray, as neutral as possible.
It can be difficult sometimes, because you may not have two neutral spots in the same picture. But if you have another picture in the same roll that has them, you can convert that one first, and then copy/paste the processing profile to the others.
