You can also go the double-negative route. Contact or enlarge onto an appropriate black and white film
to generate and interpositive (with appropriate filtration to null out the effect of the orange mask),
then onto a second sheet of black and white film to generate your actual printing neg. This route has
certain significant advantages in terms of tone or grain control, plus you can apply supplementary filtration to balance the scene just like in the field.
Not quite as in the field: you have to do it complementary.
