One embodiment of an EDR projector system comprises a first modulator and a second modulator. One method for rendering DCI-compliant image data on an EDR projector system comprises: receiving input image data, said image data comprising a plurality of image formats; determining whether the input image data comprises DCI image data; if the input image data comprises DCI image data, then performing dynamic range (DR) processing on the DCI image data; and rendering the dynamic range processed DCI image data on the EDR projector system. One DR processing method is to set the first modulator to a desired luminance level—e.g., fully ON or a ratio of DCI max luminance to the EDR max luminance. In addition, a desired minimum level of luminance may be set for the EDR projector. ## Claims ### Claim 1 A method for rendering Digital Cinema Initiative (DCI)-compliant image data on an Enhanced Dynamic Range (EDR) projector system comprising a first modulator and a second modulator, the method comprising: receiving input image data comprising a plurality of image formats;
