They should not be used in post production. These LUTs are designed only for use in LUT boxes or LUT capable monitors to preview the “base look” of ACES when shooting. There are two versions of these LUT’s, one with normal contrast and one with contrast reduced to 0.85, this lower contrast is my personal choice.ĪCES 1.0.3 LUTs for On-Set Preview normal contrastĪCES 1.0.3 LUTs for On-Set Preview lower contrast This is simply clicking 2 buttons withing Prelight. It is easy using Prelight to generate this type of file incorporating a “look” if you follow this route you will need to generate 2 LUT’s in Prelight, one incorporating the ACES "look"and one without. Working this way enables you to use a conventional film style workflow, ie no grading onset, no DIT, just a very simple data transfer and backup I have personally done this with an Odyssey and a Terradeck Bolt, we are testing and talking to manufacturers to establish what their systems need. Currently you will need to use an external LUT box between the camera and the monitor. We are currently working on versions of these LUT’s that will load directly into the monitoring of the cameras that are capable of this. If you use these LUT’s when shooting you should be able to use "standard"IDT’s & ODT’s in post with no LUT and get exactly what you saw when you were shooting. IE they contain the effect of the relevant IDT, RRT & ODT. The LUT’s are designed to take the log output of many commonly used cameras and enable you to use a standard rec 709 monitor and reproduce the "look"of having gone through a complete ACES workflow. The reason for these LUT’s is to enable low budget and very fast paced productions to have the advantages of an ACES workflow whilst shooting with their "normal"kit. The LUT’s attached below were developed by Geoff Boyle of CML and Nick Shaw of Antler Post with the cooperation of the NSC and Netherlands Film Academy. This is a new page at CML reproduced in its entirety, hopefully the links will work!ĪCES LUT’s for use in a non-ACES environment
