Where NB 2 is enough
For background swaps, color grades, and "change the shirt to red" edits, NB 2 lands the keeper in 1–2 attempts. Pro is overkill.
Where Pro pays for itself
Edits that touch the face, hands, or fine product detail. NB 2 will drift identity by attempt 3; Pro holds it across 10+ retries with no skin-tone shift.
The break-even rule
If keeper rate on NB 2 drops below 50%, switch to Pro. The retries cost more than one Pro render.
