Quote: [A digital projector has a higher gamma than a monitor because projected images in a dark surround need another characteristic than images viewed in a dim surround. The system transfer function resulting from using a DLP projector instead of a monitor is shown in the blue curve.]
It seems that they are saying that no compensation is needed, but when I see DLP projection here, the image do look at bit dark and lacking in shadow detail, maybe because they have so many lights on in the theatre to avoid trip and fall issues.
I would shoot a 18% gray card under the lighting you are using, and check that it does not read too low in the graded frames, if you convert the graded frames to BMP you should read 18% gray as about 0.458 to 0.462 or RGB= 116 to 118 or so on the 0 to 255 scale. The shareware program IRFANVIEW has a readout if you put the cursor on a spot on the image and click the mouse button it then reads out the R= G= B= value for that pixel,
If you are near midtone then it should not matter so much what gamma your viewing monitor is at, the pixel value is a better way to tell because the monitor brightness and contrast change the way the image looks anyway, you would hope the DCP projector is setup right in the theatre...
