White balance range

When I see Nate’s and other youtube NLP tutorials I see a WB range of 2000-2400. My WB ranges are
5000-5400. I pick the area outside the image, crop and launch NLP. the image is “normal” and there are no extreme color casts to my negs. Why are my ranges so different but normal looking?

I think I know why…Nate used a camera just like other posters did and I used my epson v700
