Background   This Group addresses the use of LED lighting in professional television and film production.

The challenge

The introduction of high efficiency LED lighting is leading towards a number of unintended and possibly expensive consequences for both television and film production.

Studies already undertaken show the lighting industry colour-rendering index is inappropriate for television because of the floating white point.

The aim of this group is to show how these studies could lead to the design of a “Standard camera” model, much along the lines of the human CIE “Standard observer” .
