IIRC, it’s the night scene outside the slave quarters where Qui Gon gets the blood sample from Anakin.
Right!
And IIRC, that explains why this particular shot has a totally different contrast level on BR than on theatrical 35mm: it was the only scene digitally re-rendered for the BluRay without going through a 35mm scan.
It’s more noticeable on the DVD. The majority of the DVD transfer if quite grainy, but this shot is exceptionally clean.
