  1. Hi! Could you explain what's the purpose of each LUT of the Ravengrades Look Development Starterkit? I'll expose my guesses and hope someone correct me if needed. Look Components: log_c_awg_component1_hue_ravengrade.cube log_c_awg_component2_shaper_ravengrade.cube log_c_awg_component3_tone_map_ravengrade.cube log_c_awg_component4_gamut_ravengrade.cube From what I've read, these are LUTS meant to be applied in order to a AWG3/LogC3 input. They together transform the LogC signal into a digital negative with the print characteristics of Kodak 5219. comp_LogC_AWG_v01_step5a-Rec709g24_ravengrade.cube comp_LogC_AWG_v01_step5b-P3D65g26_x65_ravengrade.cube comp_LogC_AWG_v01_step5c-Rec2020_P3D65limit_ST2084_1000nits_x65_ravengrade.cube These are Display Rendering Transforms meant to be applied after the digital negative created before and their names represent the ColourSpace and Gamma of the transform. The Creative Look is meant to be designed in a node sandwiched between component_4 LUT and last node. The Balance Node is meant to be applied directly to the LogC input. PFE LUTS - LUTs_by_Mitch_Bogdanowicz They are named K2254-K2383, which I think stands for Kodak 2254 and Kodak 2383. The Kodak 2254 is a Digital Intermediate Film and the Kodak 2383 is a Print Film, so I assume they are designed for reproducing the characteristics of the combination of these two stock. They are presented in both 3DL and Cube formats, and 33 and 65 points precision versions. The Cineon_DPX versions expect an input encoded with a Cineon gamma and the "colour space" of scanned film. The P3_viewing version outputs P3 and Gamma 2.6 for theatrical viewing with a projector. The XYZ version encodes output for DCDM. As other film print emulation LUTS normally mark the white points, I wonder which one these have embeded. P3-DPX versions I don't know what's the purpose of these ones. I guess the blank, SoftClip I and II represent different versions of handling the highlights, but as there's no "input-output" naming and they lack the "viewing" in the name, they're not meant for monitoring. P3_out_of_film_Gamut I guess it's meant to handle out of gamut values inside P3 colour space and it's meant to be applied prior to the output LUT. Despite this might look I'm affirming all the above, as I said before, these all are my guesses and would thank if anyone can confirm or correct them.
  2. First of all, I have to say it's a pleasure to be part of this community. And now, my first question in this forum. Can anybody explain why an invert Curve doesn't accurately invert the image and why getting down the luma curve to 0 shows some kind of signal? See images attached
