One of the more well known ways to use a Lookup Table, also known as a LUT, is to color correct footage so you get the contrast and detail you want. Do you want to color correct the image with the node before or after a LUT? Author Patrick Inhofer demonstrates the differences between color grading before or after a LUT in DaVinci Resolve.
- [Instructor] One question you could ask me is,…Patrick, why do we even have to prepare the LUT,…I mean I could just turn off node number two,…go to node number one, add a node after the LUT,…and now I'm just going to go ahead and pull down my…highlight detail, oh wait, wait a second…what's happening, look at that, it's clipped.…I've got no highlight detail there,…and that's the difference in working before a LUT…and after a LUT.…The moment your image passes through the LUT,…any downstream node will not be able to retrieve…the details that get clipped out.…
The moment node number one has a LUT applied to it,…all of these other nodes can't get to this highlight…detail, it's impossible, why, because LUTs are…dumb math, they're only designed…generally from 0 to 1023, the moment parts of this…image move above 1023: 1024, 1025, 2000,…those values, it's not programmed what to do…with those values, so it clips them at their upper range,…and you cannot retrieve them after the LUT,…which is why we work differently after the LUT…
Once you're familiar with the differences between log, raw, and flat recordings, explore two different methods for color correcting that footage. First, Patrick shows you how to color correct manually, using the traditional tools in DaVinci Resolve. Then, he explains how to use lookup tables (LUT), and discusses LUT strengths and limitations.
