This article synthesizes practical insights on working with D-Log M footage in DaVinci Resolve, comparing LUT-based workflows with color space transforms, and outlining strategies to maximize dynamic range, color accuracy, and overall image quality. The discussion is rooted in real-world experiences using DJI’s D-Log M across Mini 4 Pro and related drones, and it covers color management, HDR considerations, and grading techniques that help you achieve natural, pleasing results with minimal tweaking.
Two core approaches: LUT-based corrections vs. color space transforms
First you apply the D-Log M to Rec. 709 LUT from DJI’s site, which is a straightforward way to bring D-Log M into a standard color space. The second approach is to use a color space transform (CST) node in Resolve, which can move footage into a larger color space such as DaVinci Wide Gamut before grading. Using each technique, and after adjustments with color wheels and window functions, you can reach a result you’re happy with. The only thing about using LUTs is that you can only ever arrive at Rec 709 color space. Rec 709 is the most common color space currently for HDTV, but it’s a very limited color space similar to sRGB. Using a color Transform node in Resolve you can bring your footage into a bigger color world and you’ll be amazed by the increased dynamic range and colors.
In practice, many users work in DaVinci Wide Gamut and then output Rec 2020 in HDR for platforms like YouTube or Vimeo, which aligns with modern HDR displays and most smartphones. Almost all LUTs tend to “dumb down” footage to Rec 709, whereas CSTs (when used correctly) preserve wider gamuts and can reveal more dynamic range and color nuance. For a workflow that emphasizes maximal color space freedom and HDR potential, CSTs are typically preferred at the start of the node tree, with LUTs optionally used later as a controlled finishing step.
How to set up color management for D-Log M in Resolve
From color management perspectives, choose either DaVinci YRGB or DaVinci YRGB Color Managed depending on your workflow. If you enable Automatic color management, the input color space may default to Rec. 709, which can be overly simplistic for D-Log M. For DJI footage, it’s often beneficial to set the input color space to the appropriate D-Log M profile (DJI D-Log / DWG or similar, depending on your drone) so that Resolve applies the correct input transform before grading. In the Davinci Wide Gamut workflow, set the top line to Color Managed, select Custom, and ensure the input color space is set to D-Log for DJI Mini or related cameras. This approach uses an Input Color Transform rather than a LUT to achieve the correct starting point.
Then, in the color page, choose Davinci Wide Gamut as your color space, with a timeline luminance target of 1000 nit and an output of Rec 2020 with ST 2084 1000 nits for HDR workflows. HDR metadata should be enabled in the master settings, and HDR 10 metadata should be selected for YouTube since Dolby Vision isn’t always supported for uploads. Set the scope style to HDR to visualize the full 100 nits to 1000 nits range. If you’re on a Mac with a P3 display, ensure your monitors are set to high quality and proper color profiles for accurate viewing.
Practical workflow guidance: LUTs vs. CSTs for D-Log M
DJI provides a D-Log M → Rec. 709 LUT for each camera (Mini 4 Pro, Mavic 3 Pro, etc.), which is commonly used as a finishing node or as an initial correction. Some colorists place the LUT at the end of the node tree, after all grading nodes, to constrain its influence. Others prefer CSTs at the start to expand the color space before any grading, and then apply LUTs (if desired) later to fine-tune to Rec. 709 or Rec. 2020 for HDR delivery. The CST approach lets you unlock a broader color gamut and more dynamic range, which is particularly beneficial for scenes with wide tonal variation or intense highlights.
In terms of practical results, many users report that D-Log M benefits from a gentle S-curve, a modest lift in contrast and saturation, and careful WB adjustments rather than heavy LUT-driven transforms. A CST-based workflow often reduces the risk of clipping in highlights and preserves more color nuance across the image. If you’re new to log formats, starting with a CST to move into a wider color space, then applying a tailored primary grade and selective secondary corrections, can yield more natural results with less trial-and-error tweaking.
Color correction tools and techniques that help with D-Log M
DaVinci Resolve provides a rich toolbox beyond LUTs and CSTs. Primary wheels (lift, gamma, gain) let you shape shadows, midtones, and highlights; color wheels enable precise balance across tonal ranges. Curves (RGB, Hue vs Hue, Hue vs Sat, etc.) let you sculpt color and contrast with fine control. Secondary grading with qualifiers and Power Windows allows targeted adjustments to suits, shirts, skies, or other specific objects without affecting the entire frame. The tracker can animate Power Windows to follow moving subjects, enabling consistent adjustments across a shot.
Nodes are the building blocks of color grading in Resolve. The first node is typically a balancing node, while subsequent nodes isolate and enhance specific areas (e.g., sky, skin tones). Using multiple nodes allows you to create complex looks without flattening image quality. For HDR workflows, Resolve Studio supports HDR formats, tone mapping for HDR, and advanced color space transforms to maintain fidelity across devices.
Video and image assets: infographics and tutorials to consider
To deepen understanding, refer to respected tutorials that demonstrate CSTs and LUT-based approaches for D-Log M, including how to configure input spaces, color pipelines, and HDR metadata. Practical examples show how to compare Rec. 709 outputs from LUTs against wider Rec. 2020 targets achieved via CSTs and wide gamut workflows. Visual demonstrations of the differences in highlight handling, color richness, and overall dynamic range can be especially helpful when deciding which workflow to adopt for your drone footage.

Deliverables and final steps for D-Log M projects
When you’re ready to export, choose a delivery format that matches your HDR target (e.g., Rec. 2020 with ST 2084 for HDR10). If you publish to SDR platforms, you may still grade in wide gamut with a Rec. 709 output, applying appropriate tone mapping. For long-form or 4K content, ensure you export with the correct metadata and color space information so playback devices and platforms interpret the grade correctly. If you need a quick sanity check, compare a reference frame against a known look and adjust the grade to maintain consistency across shots and scenes.
In summary, both LUT-based workflows and color space transforms are valid for D-Log M, but CSTs typically offer more flexibility and higher potential for preserving dynamic range and color nuance. A practical approach is to develop a robust CST-first pipeline in Resolve, use primary and secondary grading to shape the look, consider a DJI LUT as a finishing touch if needed, and ensure HDR metadata and color management settings align with your delivery targets. This strategy often yields more natural, pleasing results with less fiddling of color wheels, curves, and windows compared to relying solely on LUTs.
