Temperature: cool ← → warm · Tint: green ← → magenta. Applied after the picker, so use these to push a deliberate cast on top of a neutral result.
Each row builds one output channel by mixing the three input channels. If a row's numbers add up to more than 100%, that channel gets brighter; less, and it gets darker — so editing the matrix shifts exposure as a side effect. Normalizing divides each row by its own total, so every row sums to 100% and the mix changes colour without changing brightness. Leave it off if you want a row to deliberately lift or drop a channel.
Defringe removes the purple/magenta halos IR lenses leave on high-contrast edges. It smooths colour only — edge sharpness is unaffected. Start low; too much desaturates fine detail.
