About This Tool
Cinematographers and studio lighting technicians utilize micro-reciprocal degrees (mireds) to calculate exact warming or cooling gel corrections when matching disparate light sources. In this color science evaluation utility, chromatic parameters are represented by three inputs: a baseline color temperature metric ($V_1$), a spectral shift coefficient ($V_2$), and an optical filtration density divisor ($V_3$).
The utility processes these variables to yield the primary mired shift metric ($[V_1 imes V_2] / max(0.01, V_3)$), the chromatic intermediate factor ($sqrt{max(0, V_1 imes V_2)}$), and the relative transmission balance percentage ($[V_1 / (V_1 + V_2)] imes 100$).
### Distinct Worked Calculation Evaluating a tungsten-to-daylight conversion gel array: - Baseline Color Metric ($V_1$): 64 - Spectral Shift Coefficient ($V_2$): 12 - Filter Density Divisor ($V_3$): 8
Step-by-step results: - Primary Mired Metric: $(64 imes 12) / 8 = 768 / 8 = 96.00$ - Chromatic Root Factor: $sqrt{64 imes 12} = sqrt{768} approx 27.71$ - Transmission Balance: $[64 / (64 + 12)] imes 100 = (64 / 76) imes 100 approx 84.21%$
### Local Processing Note All chromatic math operations run 100% inside your client-side browser tab. Light fixture Kelvin temperatures and lighting filter presets are never transmitted across any network connection.

Frequently Asked Questions
What is a mired in photographic lighting?
A mired (micro-reciprocal degree) equals 1,000,000 divided by the color temperature in Kelvin, providing a linear scale for optical filter calculations.
How does positive versus negative mired shift affect lighting?
Positive mired shifts warm the light toward amber/orange (CTO gels), while negative mired shifts cool the light toward blue (CTB gels).
Are your lighting fixture entries stored in an online database?
