![]() The end goal is to have the same image look perceptually identical on two different viewing devices. Technical LUTS – These types of LUTs are designed to transform an image from one colour space / gamut to another. He broadly divides LUTS into Technical LUTS and Creative LUTS. In this post over on Mixing you can learn a little bit about the different types of LUTS as colorist Patrick Inhofer defines them. What are the different types of LUTS for? This short video from Ground Control Color will give you a good overall understanding of the premise of a LUT and is humorous, which is a bonus. ![]() In essence, what a 3D LUT does is take an input value and generate a new output value, for each and every RGB triplet. This explanation on LUTS from Light Illusion is also well worth a read and is also helpful on explaining 3D LUTS. This allows for greater control, for example, increasing contrast without increasing saturation. Here you can create “ a set of the combination of three inputs defining the combination of R, G, and B values not of one where each input refers to one unique output”. With a 3D LUT you have more control over transforming these values separately and in combination. So if you increase contrast in your image, you will increase saturation, because the values are tied together in the simple chart, take this and make it that. With a 1D-LUT you’ve got some control, but not that much control. I’ll paraphrase it as best I understand it. This explanation over on the Fuji film site is mildly technical, but still explains things to an accessible level of detail. What’s the difference between a 1D-LUT and a 3D-LUT? ![]() For example in the red channel use LUT A to make 1 = 7 but in the blue channel use LUT B to make 1=15. This can happen to the image over all or per colour channel (RGB). If the input is 0 make the output 5 – or whatever, these numbers are arbitrary, it is just a conversion matrix – take this, make it that.

Used to preview the transform on the P6K or external monitors. In-Camera/On-Set Rec709 LUTs: Same as above but created at x33 precision for compatibility. Post-Production Rec709 LUTs: The P6K BMDFilm to Alexa LogC conversion combined with the three Rec709 output LUTs above. For a comparison of all four scroll down. Standard, Wide Dynamic Range ( WDR), WDR Highlights and WDR Roll-Off. It won’t be an exact match to an Alexa, but can sometimes speed up image balancing.ĪRRI LogC2Video LUTs: The latest ARRI LogC to Rec709 LUT in four different curves. P6K to Alexa LogC ISO400 and ISO800 Balanced LUTs: Same as above, but the matrix has been adjusted to remove the typical Alexa green cast. ![]() These LUTs will require a Rec709 output conversion such as one of the ARRI LogC2Video LUTs below or any other LUT or Color Space Transform designed for ARRI LogC footage. Then the LUT internally increases the exposure to match native ISO800 footage. The latter allows you to decode BRAW ISO800 images as ISO400 to prevent excursions above 1.0 input. Two main versions, Input Scaled to work with data above 1.0 input, and Standard to work with software that doesn’t support the former feature. ![]() P6K to Alexa LogC ISO400 and ISO800 LUTs: Transform Blackmagic Design Pocket 6K Film Gen 4 to match the Alexa in it’s native LogC format. To find out why, read The Creation Process below. And it offers many benefits over using a LUT. This is the same method used by high-end post houses to match digital cameras. I then used this data to build a custom 3×3 matrix that accurately matches both cameras. On receiving the camera I proceeded to profile the sensor using the techniques I had previously used to profile the Alexa sensor and various film stocks. The idea was to have a smaller and lighter camera that would live on a gimbal. In November 2019 I purchased a BMPCC 6K to complement the ARRI Alexa I normally shoot with. ![]()
