- Improved Cast Removal — neutral greys no longer drift slightly green. Cast Removal now balances each colour layer at the midtone as well as the shadows (a true two-point per-channel gray balance), measured only on near-neutral pixels so green-heavy scenes (foliage, skin) can't pull the balance. Previously the midtone leaned on a single luminance reading that is mostly green, leaving a faint green cast on many C-41 conversions. The default look shifts slightly toward neutral.
