Cinesoft Spectral Overview
Empirical Data Supporting the CINESOFT'S
Distinct Advantage Over Competing Fixtures
Overview
THE CINESOFT 50,100 & 200 BY CINEMILLS HAS A PROPRIETARY TECHNOLOGY KNOWN AS CBET
(Color & Brightness Enhancement Technology) AND IS THE ENGINE THAT MAKES THE CINESOFT THE
HIGHEST PERFORMING LED SOFT PANEL IN ITS CLASS.
TO UNDERSTAND WHY CBET IS A SUPERIOR TECHNOLOGY WE MUST FIRST UNDERSTAND LED
PERFORMANCE METRICS AS IT RELATES TO CAMERA IMAGING.
THE THREE TENANTS OF LED PERFORMANCE
•
•
•
Spectral Power Distribution Function (“SPDF”)
Color Rendering Index (“CRI”)
Delta UV for the Camera Image
The above (SPDF, CRI & DELTA UV) represent the three most important aspects as it relates to
lighting quality as rendered onto a Camera’s Image.
1.
SPDF translates directly to the color fidelity of the image captured by a camera.
CRI (Color Rendering Index) describes the color fidelity of the image as per the human eye.
2.
……… According to Science & Technology Council of the Academy, CRI as it relates to LED’s
and motion picture capture is a “Necessary Condition”, but not a “Sufficient Condition” because
of the different spectral response of the motion picture camera and the human eye.
3.
Delta UV describes how much the white light from a lighting source is as close to the
white spectrum of the Sun also referred to as “black body radiation.” This has a direct effect
on the green/magenta cast. The recommended Delta UV is between -0.002 and 0.002 in order to
minimize the green/magenta cast from the lighting source.
SPDF(Spectral Power Distribution Function) and it’s signifcance as it relates to Camera Imaging.
* SPDF relates to the color fidelity as captured by a camera, High CRI 90+ is also important.

Academy.

Upper colors: captured by a camera under 3,200K tungsten halogen.
Lower half colors: Simulated Colors captured by a camera under
the ideal 3,200K LED lighting – simulated by Science & Technology
Council of the Academy.
Upper colors: captured by a camera under 3,200K tungsten halogen.
Lower half colors: Colors captured by a camera under 3,200K LED
lighting with the SPDF shown in the left. Although CRI is more than
95, colors are different from the colors under 3,200K tungsten
halogen because of the different SPDF.
SPDF (Spectral Power Distribution Function) and it’s importance for Camera imaging.
* SPDF relates to color fidelity captured by a camera, High CRI 90+ is
- 3200 Tungsten
also important
- 3200 LED w/CBET
CCD/CMOS Image sensor’s
spectral response is saturated
a er 620nm. Therefore, the
peak of the red light does not
ma er to the image sensors of
a camera

closest to the ideal SPDF suggested by Science & Technology
Council of the Academy.

Understanding the Digital Camera Image Sensor
The image sensors used for a digital camera are based on two structures, three panels with optical separation
prisms, and a one panel Bayer Color Filter.

THE CINEMILLS CINESOFT HAS THE BEST
SPECTRAL QUALITY ON THE MARKET
1. Color & Brightness Enhancement Technology (CBET) makes the SPDF of the
CINESOFT 50,100 & 200 (with a CCT of 3,200K) the closest replication of SPDF
from the light emitted from a 3,200K Tungsten Halogen Fixture.
2.
The SPDF of 5500K light, emitted from the CINEMILLS CINESOFT is also relatively
the closest LED light source similar to sunlight at 5,500K (Illuminant D55) as
compared to any other LED products on the market.
 The best color fidelity can be achieved using CINEMILLS LED lighting products along
with digital cameras.
 Less time and money is required for Digital Intermediate Color Correction during
post production as a result of using the CINEMILLS CINESOFT products.
