THE EXTENSIVE LED TEST

in cooperation with NRK/FNF 

 

WE HAVE FOCUSED ON HOW THE CAMERA SEES THE LIGHT ON HUMAN SKIN, FROM THE DARKEST BROWN TO THE LIGHTEST HUES. THE TEST IS MEASURED BOTH WITH DIRECT AND REFLECTED LIGHT. 

 

THE TEST IS MEASURED IN THE CAMERA FRIENDLY TLCI/EBU STANDARD AND CRI.  THE TEST IS AVAILABLE AS A BLIND TEST, NOT INFLUENCED BY NAME OR PRICE.   

DOWNLOAD ARRI RAW FRAMES from Dropbox

 

Download a ZIP with a single frame from the arri raw image. The image is represented with a number only. We would love to have your comments on what you think is the preferred LED light - and then we can send you the name of the light-unit - referring to the number.

Download the different scenes as arri raw image or just a single frame.  The image is represented with a number only. We would love to have your comments on what you think is the preferred LED light before you look at the Facit / Diagram with the name of each unit. 

CREATE YOUR OWN JPEG SAMPLES 

 

If you don´t have the possibility to compare the original ARRI RAW files, we have created some JPEG stripes of test-pictures for you to test with your own eyes. There will always be a possible error when converting from color space to color space / ARRI RAW to Jpeg. The conversion is uniform for all test light units.

THE IDEA BEHIND MEASURING REFLECTED LIGHT 

 

This is probably the first time a test has been measured both with standard direct light  - and in-direct light.

 

Read more about why we measured in-direct light. 

A VERY PRECISE MEASUREMENT     

 

Read more about how we measured the test with a Stellarnet Black Comet  spectrometer, calibrated to Bentham Instruments' halogen lamp.
