This feature is particularly useful for pre-correcting image workflows and ensuring consistent colors in video content. Overall, the LUT Image tool offers innovative and precise solutions for color manipulation and correction.

LUT Ripping workflow

Utilizing the LUT Ripping workflow unveils a streamlined and efficient process for exporting and applying external modifications to the LUT Image, allowing for seamless integration of color adjustments into the post-production pipeline. This workflow offers a simple yet powerful method for extracting the LUT image from ColourSpace and applying external color corrections. By exporting the LUT image, users can then apply their preferred color correction tools to manipulate the image’s colors. Once the modifications are made, the LUT image can be re-imported into ColourSpace, automatically generating a new LUT that matches the applied changes. This workflow not only saves time but also ensures accurate and consistent color adjustments, making it an invaluable tool for precise color correction in the post-production industry.

LUT Image Export

Exporting the LUT image enables users to seamlessly transfer the color manipulations made in external systems back into ColourSpace, facilitating a cohesive and harmonious integration of desired adjustments. The exported LUT Image contains Null LUT data in the colored columns of a .tif image, which can be loaded into any external system for color manipulations. This allows users to apply color correction settings in grading systems or any graphics program. After applying the desired changes, the LUT Image can be re-saved and loaded back into ColourSpace, where a LUT matching the applied grade changes will be automatically generated. This workflow ensures that the adjustments made externally are accurately incorporated into the color correction process, enabling precise and impactful color correction for video content.

LUT-based Workflow Correction

When pre-correcting image workflows with undesirable changes, adding different reference images to Null LUT Images for variable compression and processing them through the same path can help null compression artifacts. This LUT-based workflow correction technique offers a precise method to counteract unwanted changes caused by image processing. Here are four key steps involved in this process:

  1. Load the Null LUT Image into ColourSpace along with the reference images.
  2. Process the images through the same path, applying the desired compression settings.
  3. Average the processed images together to nullify compression artifacts.
  4. Import the averaged images back into ColourSpace, where a new LUT is automatically generated to match the changes caused by the image processing.

By utilizing this workflow correction method, content creators can ensure accurate and consistent colors in their video content, especially when dealing with material conversion via codecs or uploading to platforms like YouTube.

LUT Image Manipulation Workflow

The workflow involving the manipulation of LUT Images provides an effective means of adjusting and enhancing the color characteristics of images, allowing for creative expression and the attainment of desired visual outcomes. This process is particularly useful in post-production and broadcast industries where accurate and consistent colors are essential. By loading the calibration LUT into ColourSpace and adding a reference image, the LUT Image can be exported with the applied LUT. This exported image can then be loaded into a graphics program, such as Photoshop, where it can be directly altered using the reference image as a guide. The manipulated image is then exported and the changes are burnt into the LUT Image. When imported back into ColourSpace, a new LUT is automatically generated, ensuring precise color correction and manipulation.

LUT Image Film Emulation

The process of emulating the characteristics of film through the manipulation of LUT Images offers a creative approach to achieving desired visual effects and capturing the nostalgic essence of traditional film photography. By loading the LUT Image into a graphics manipulation program, users can make precise changes guided by an inserted reference image. The manipulated image can then be exported, with the changes burnt into the LUT Image. When imported back into ColourSpace, a new LUT is automatically generated, allowing for accurate color reproduction. This workflow enables users to experiment and create unique looks by adjusting various parameters, such as color temperature, contrast, and saturation. The LUT Image Film Emulation technique empowers professionals in the post-production and broadcast industries to push the boundaries of visual storytelling and deliver innovative content to their audiences.

LUT Mixing

Graphics program-based LUT mixing allows for the combination of separate LUT Images, enhancing the creative possibilities and expanding the range of visual effects that can be achieved. By utilizing the Layer Reveal capability of graphics programs, one LUT Image can be placed over another, revealing the second image below. This technique enables the creation of unique and complex color grading effects. To further illustrate this concept, consider the following table:

LUT Image 1 LUT Image 2 Resulting LUT Image
Original Original Original
Original Emulated Emulated
