Post effects are visual effects that you can apply to the whole screen. Lens Studio has a number of such built in effects that you can easily add and modify. Because Color Correction is by far the most commonly used Post Effect, this guide is broken out into two sections: the Color Correction Post Effect and all of the other Post Effects.
Color Correction Post Effect
The Color Correction Post Effect uses an input color lookup table image to adjust the coloring of the Lens. Image adjustments (saturation, exposure, color balance, etc.) are performed in an external editor like Photoshop and applied to the lookup table. The lookup table is then imported into Lens Studio and added to a Color Correction Post Effect object.
Lens Studio includes a number of built-in Color Correction textures if you are unable to create your own. They can be added to your project in the
Objects panel by selecting
Add New -> Color Correction.
Download the Color Correction Lookup Table
To make your own custom Color Correction Post Effect, download the below base lookup table. You'll be making your modifications to this image.
Modify the Color Correction Lookup Table
Open the base lookup table image in Photoshop or a similar image editing tool. You'll be making your adjustments to this lookup image. Add a reference photo as a layer above the lookup layer. Then, add adjustment layers above both the reference and the lookup. In the example below, we've added simple
Color Balance adjustment layers to give the Lens a pink tone.
Use your reference layer and the added adjustment layers to tune your effect.
Before export, hide the reference layer. Your adjustment layers will apply to the still visible image lookup table.
Export the lookup image with your newly added adjustments as a PNG.
The Color Correction Post Effect object only supports a non-compressed PNG. Compressing the PNG or using a JPG will result in noticeable artifacts.
Using the Color Correction Lookup Table

Add New button in the
Objects panel. Then, select
Post Effect -> Color Correction.
Add your adjusted lookup table texture to your project by dragging it to the
Resources panel. Then, in the
Objects panel, select your newly added
Post Effect object and set its
Main Texture to the adjusted lookup table texture in the
Inspector panel. You should now see your image adjustments applied to your Lens. You can also tune the intensity of the
