The guide below describes how to prepare a LUT file suitable for use in Face AR or the Banuba AR Web Studio. Keep in mind there is a big difference in what the Face AR SDK expects in terms of this file, vs the Video Editor SDKSDK.
Keep in mind you will need some photo / image editing software for this. This example will be using Adobe Photoshop as a reference on how to do this.
-
First of all you will want to download the following image that will serve as a base for making your custom LUT.
Base Image:
-
Import the image from step one into a photo editing software of your choice.
-
Open a reference image, such as the following on in the same image editing software:
-
Apply adjustment layers to the reference image from point 3 till you achieve your target visual effect.
For this example we use the Curves, Channel Mixer, and Photo Filter adjustment layers with custom settings to achieve a slightly faded retro look.
-
Transfer these layers on top of the the base image you opened in your editor in point 2.
-
Save/Export the resulting image from point 5 as a .png with no or minimal compression.
Your custom LUT is now ready for using in Face AR SDK filters or the Web Studio!
