Tom Evans January 18, 2019 Share January 18, 2019 Can someone explain to me the concept of using transform functions instead of LUTS, what is the difference? Link to comment Share on other sites
dermot.shane January 19, 2019 Share January 19, 2019 cleaner math, look at a transform & a lut over a grey scale contrast and compare not all LUTs are crap, but... far too many are Link to comment Share on other sites
Tom Evans January 19, 2019 Author Share January 19, 2019 So an OFX node taking us from Alexa log to rec709 would draw the same curve as the standard log2rec709 Alexa lut, just with cleaner math? Link to comment Share on other sites
Orash Rahnema January 19, 2019 Share January 19, 2019 Also, if you don't check Luma and sat mapping but you trim by hand, there is not clipping after the transform Link to comment Share on other sites
dermot.shane January 19, 2019 Share January 19, 2019 it's been many years since i last used a LUT beyond reverse engineering it, the math errors of some of the stuff the cleints drag through the door are amazing, and not amazing in a good way either... 1 Link to comment Share on other sites
