Skin Tones and Sensitivity<br />
The Determination of<br />
Static and Dynamic Quality<br />
Parameters<br />
With the flexibility and dynamic features of LED technology, it was just<br />
a question of time until these advantages were fully exploited for<br />
quality control and testing applications. Over the past months teams<br />
from the camera and lighting units at ARRI have joined this trend to utilize the<br />
full potential of LEDs in combined projects with our R&D and testing labs.<br />
We are confident that this “camera-light-coupling” will enable a whole new<br />
world of measuring devices and new features to be developed for service<br />
teams and end users.<br />
Intelligent, Dynamic LED Lights<br />
for Special Applications<br />
The three busts were used to verify the skin<br />
tone reproduction of camera systems<br />
As part of a bachelor thesis novel approaches<br />
to the pictorial assessment of camera systems<br />
have been developed. One component of<br />
this work has now been realized in close collaboration<br />
between ARRI Quality Management<br />
in Munich and ARRI Lighting in Stephanskirchen.<br />
For a reproducible analysis of the very important<br />
aspect of skin tone reproduction of<br />
camera systems, artificial busts have been<br />
created by special effects make-up artist<br />
Birger Laube ( PA N D O R U M ). The color of<br />
these busts largely corresponds to the color<br />
of human skin tones.<br />
The three busts with European, African and<br />
Asian skin tones were placed in a studio<br />
set-up, which is lit with innovative LED illumination.<br />
This allows the verification of the skin<br />
tone reproduction of camera systems under<br />
realistic, yet reproducible conditions in artificial<br />
light as well as daylight situations. Another<br />
application of this test scenario is the<br />
comparison of camera systems in terms of<br />
sensitivity and noise.<br />
