# Adopting Custom LUT Filters
A **LUT (Lookup Table)** is a filter that applies color effects to photos and videos in a simple way. PRISM Live Studio provides a LUT effect filter that is available for all graphic-based sources. While PRISM Live Studio offers various LUT filter presets, you can also use custom filters from your own LUT file.

To apply a custom LUT filter, right-click any source you want to use it on and select **Filters**. You can also access the **Filter** button at the bottom of the source’s **Properties** window.
Right-click a source and select Filters.
In the **Filters** window, click the **Plus (+)** button in the **Effect Filters** section and select **Apply LUT**.
