Adding the presets to your photos is not difficult at all. It literally takes a few clicks once you get the hang of it. Think of it as a copy & paste process. All you need besides the presets is the free version of the app LightRoom (free to download).
The price for the pack of three presets is $49.99 but like I mentioned, you can use my code ANA_20 to get 20% off any preset purchase! Below I have included some before & after photos, so you can see what the presets look like!
