Choosing the ACES Output Transform for DLP-Based VFX Approval

[nick (Nick Shaw)]

I disagree with Nick here. DI uses a native D60 white point while you are using a DCI white point with D60 simulation. You will get some limits that DI will not get, notably getting a hue shift when whites are clipping. Ideally, you should do just like DI and calibrate the projector to D60 and not use the simulation in ACES.

It’s certainly true that the ideal would be to set the projector to P3-D60 2.6 gamma, and use the appropriate Output Transform. Hence my comment:

Unless you have the option to manually enter the chromaticity coordinates for D60 white.

My response was on the basis that the OP was only able to set the projector to DCI white, in which case “P3-DCI (D60 simulation)” is the next best thing. You are right that the appearance will vary slightly from that of a true D60 projection at the very top end.
