Digital Cinema Initiatives, LLC (DCI) was created in March, 2002, and is a joint venture of Disney, Fox, Paramount, Sony Pictures Entertainment, Universal and Warner Bros. Studios. DCI's primary purpose is to establish and document voluntary specifications for an open architecture for digital cinema that ensures a uniform and high level of technical performance, reliability and quality control.

It announced a new suggestion of 3D peak white luminance on July 15th, the original content is as follow:

For 3D presentations utilizing legacy lamp technology, the peak white luminance should be 24 cd/m2 ± 6.9 cd/m2 (7 fL ± 2 fL) measured at the center of the screen through all filters and lenses, i.e., light level to the eye. Relative luminance uniformity should be consistent with current SMPTE specifications.

Given the increased light level capabilities of 3D RGB laser illuminated projectors and multi-projector installations, peak white luminance for such projection systems should be 48 cd/m2 ± 6.9 cd/m2 (14 fL ± 2 fL) measured at the center of the screen through all filters and lenses, i.e., light level to the eye. Relative luminance uniformity should be consistent with current SMPTE specifications.
