"What LUTs are and are not
- Color grading is an extremely important part of filmmaking and photography process.....
- It is extremely important to follow a few simple rules when it comes to color grading in order to make sure it enhances your footage. When you’re using 3D LUTs as a part of your color grading process, it is even of higher importance to follow these simple rules.....
- LUT stands for Look Up Table. In short, LUT is a table used to map one color space to another. For example, a LUT can remap a log image into Rec.709 space or it can be used to apply a preset look for any given image or footage.
- LUTs are commonly used to calculate preview colors for a monitor or digital projector of how an image will be reproduced on another display device. However, LUTs may be used as a starting point for color grading......
LUTs workflow
Now that we have better understanding of what LUTs are and what they can and cannot do to your image, let’s see how we can make the most out of them.
- Step No. 1 – Normalising the image
The very first step we should perform when working with log footage or images is to normalize them. It’s extremely hard to impossible to judge exposure from log images let alone color. Therefore, before doing any basic corrections, we should apply a log normalisation LUT to our image or footage in order to re-map it into a workable looking image. It is possible to manually normalise footage or images however it is very time consuming task and can require a lot of trial and error before nailing the correct image.
- Step No. 2 – Color correction
- Step No. 3 – Creative color grading
The last step of using LUTs is actually applying the creative LUT.
Once we have our image nicely balanced we can go on a apply a creative LUT that would be a starting point for our color grade.
Remember, LUTs should be used as a starting point for your final color grading and not as a final look. While sometimes you may be completely satisfied with the result achieved with a LUT as-is, most of the time you will need to make some minor adjustments to better suit your image. No two images are the same so adjustments will be required most of the time.
Normalize your footage as the very first step.
Once your footage is normalised, it’s time to color correct it and balance it.
Applying a creative LUT is to be done only after we normalised our image and color corrected it
Last step would be secondary corrections....
It’s very important to understand that while LUTs can elevate your brand and greatly enhance your color grading, they are not some magical solution to all your color grading needs. Using LUTs requires some basic knowledge and correct workflow to get the best results.
