25 presets. Imagine 25 warm, fresh donuts ready to glaze their way into your donut hole. Awww yeah... I love Luminar so much and figured out a few unpredictable ways to push the controls and create some interesting results. There is a wide variety of filters in here. Some work great with landscapes, some are better with people/portraits, and some are best for architecture. There are also some radical B&W filters included.
Now, you may notice that some of these presets give fairly strong and robust results. Keep in mind that you can take that slider on the thumbnail of the preset and drop it to 80% or 50%, or whatever looks best. Remember the thing about presets: it really depends on the photo you put into it. If it's a bright sunny day, the results of one filter will look completely different than if you are shooting the inside of a dark cathedral.
Also, keep in mind that these presets can be a great starting point. You can still add more vignetting, more saturation, and add other filters... that's the beauty of Luminar!
