Color Temperature Mired Shift Calculator
Work out the mired shift (and the CTB/CTO gel) needed to convert one color temperature to another — match tungsten to daylight and back.
Color-correction gels are rated in mireds because equal mired shifts look equal across the spectrum. Converting 3200 K tungsten to 5600 K daylight needs about −78 mired of cooling — Full CTB. Going the other way (daylight to tungsten) uses CTO. This gives the exact mired figure to pick the right gel.
