However, including equations for technical papers and implementing useful, appropriate options are two different things an I have now tried to put LUTCalc into the right position. LUTCalc has long included various high dynamic range curves, including the two which are establishing themselves as standards: Perceptual Quantisation (PQ) and Hybrid-Log Gamma (HLG). I've been playing around taking and analysing test images on an a7s the result of which is my estimation of the Cinegamma 3 and Cinegamma 4 curves (Cinegammas 1 and 2 being renamed Hypergammas). This update features a couple of new curves, some important changes to the way others work, a new tool for targeting different displays and the start of changes to the interface.įirst, a relatively simple new feature. LUTCalc v3.1 Update - 1t June 2017 - HDR, Cinegammas, Display Colourspace Conversion and responsive design More details about LUTCalc can be found in the ' Features' section Back To Top This is an ongoing process and I am grateful for the help I have had in checking results and discovering when I have made mistakes! LUTCalc allows you to set all levels as you wish, but also offers simple presets to help consistency in various applications. I have also come to realise that at present it is far too easy for LUTs to behave inconsistently between bits of software (or cameras). I have worked to make the tools familiar to me in my work with film and video cameras for example colour temperature can be set directly but also with a CTO / CTB slider akin to lighting gels. Many of my clients do not currently want or need log, and I frequently bake-in my personalised looks developed with LUTCalc. The charts and exposure values have also helped me to understand the way that modern cameras handle wide exposure ranges giving me good, consistent results. If shooting log I also make grading versions so that post can start off working with 'my' look. I use it to create MLUTs for the Sony F cameras I currently most often use. I have written LUTCalc from scratch to help me with my day to day work. My name is Ben Turley and I am a professional lighting cameraman and DoP in the UK. What began as a hobby gradually became more of an obsession which has developed into a flexible tool for creating and then shooting with 'looks'. It started out as a simple spreadsheet for generating S-Log2 exposure shift LUTs for Sony's F5 and F55 cameras. To make a contribution please use the drop down menu here, there are several contribution levels to choose from.LUTCalc is a desktop app for generating, analysing and previewing 1D and 3D Lookup Tables (LUTs) for video cameras that shoot log gammas. If you find these LUT’s useful please consider buying me a coffee or other drink. But only share via a link to this page please. Please feel free to share a link to this page if you wish to share these LUT’s with anyone else or anywhere else. In addition I have include the same LUTs but with Legal range input levels for use on Atomos and other recorders that record ProRes in using Legal Range. There are also minus1 and minus2 LUTS that have 1 and 2 stop exposure shifts for footage that has been shot brighter than the base exposure. There are 65x LUT’s suitable for grading as well as 33x LUT’s for monitors or grading software that doesn’t support the higher quality 65x LUTs. As usual I have include different versions of the LUT. Note: These LUTs are for S-Log3 and SGamut3.cine from the FX9. So you won’t see a big difference, it’s subtle, but I think it really is better.Ĭlick Here to download the ACs709 For FX9 LUT set. The idea isn’t to create a new look, just to help get rid of the tint. The difference between this LUT and Sony’s original s709 LUT is very small. So I now have a new version of the LUT which really does help combat the green tint. I recently created an experimental LUT to minimise this tint but some people found this tended to push some images slightly magenta. I believe that this is because originally the s709 LUT was designed for the Sony Venice camera and the FX9 is very slightly different. Many users of the FX9 that have been shooting S-Log3 are finding that when they add the standard Sony version of the s709 LUT that their pictures have a slight green tint.
