Convert DNG to CUBE

Understanding DNG and CUBE file formats

DNG (Digital Negative) is an open, lossless raw image format developed by Adobe. It is widely used by photographers to store unprocessed image data from digital cameras, preserving maximum image quality and flexibility for post-processing.

CUBE files are 3D LUT (Look-Up Table) files used in color grading for video and photo editing. They store color transformation data, allowing users to apply specific color effects or corrections to images and videos in compatible software.

Why convert DNG to CUBE?

Converting a DNG file to a CUBE file is not a direct image-to-image conversion. Instead, the process involves analyzing the color grading or look of a DNG image and creating a LUT (CUBE) that can replicate that look on other images or videos. This is useful for filmmakers and photographers who want to apply a consistent color style across multiple projects.

How to convert DNG to CUBE

To convert a DNG file to a CUBE LUT, you need to extract the color adjustments made to the DNG and export them as a LUT. This typically involves using photo editing software that supports LUT export. Here’s a common workflow:

1. Open your DNG file in Adobe Photoshop or Adobe Lightroom.
2. Apply your desired color grading and adjustments.
3. In Photoshop, go to File → Export → Color Lookup Tables.
4. Choose the .cube format and export your LUT.

Alternatively, you can use 3D LUT Creator or DaVinci Resolve:

• Import the DNG, apply your color grade, and use the Export LUT feature to save as a CUBE file.

Best software for DNG to CUBE conversion

• Adobe Photoshop – Industry standard for photo editing and LUT export.
• Adobe Lightroom (with plugin support) – For color grading and LUT creation.
• 3D LUT Creator – Specialized tool for LUT creation and export.
• DaVinci Resolve – Professional color grading software with robust LUT export options.

Summary

While you cannot directly convert a DNG image to a CUBE file, you can create a LUT that captures your color adjustments from a DNG and export it as a CUBE file using professional photo or video editing software. Adobe Photoshop and DaVinci Resolve are highly recommended for this workflow.
