LUT is an acronym for LookUp Table. Basically, the LUTs are a filter applied to your image that will map its pixel values to values defined in a table. Since this mapping is predefined, you can only change its opacity, that is, how strong it is applied.
However, the main advantage of LUT is that due to this mapping, the effect applied to photos can range from simple tonal tweaks that make an image smoother or lighter to some very complex ones allowing you to dramatically modify the aspect of your photos.
But where to get them? LUTs are usually priced, but from time to time the same vendors release some high quality free LUTs. I’ve browsed through a bunch to end up with the 5 ones I’ll mention here.
These LUTs will work on software with proper support, like Adobe Lightroom, Affinity Photo, or Adobe Photoshop. On1 Photo Raw still doesn’t have LUT support but it’s coming up in the next update later this year.

Applying LUTs in Affinity Photo
To add a LUT to your image in Affinity Photo, you just need to add the LUT layer from the Adjustments panel.
Once there, click the Load LUT button to browse your files and load the desired LUT.
Once you load it, you can click the Add Preset button to add it as a preset to quickly applying it the next time you need it.
