So each preset/filter above, are all ones I consistently use for instagram. Of course it's not going to instantly make your photo perfect, because depending on lighting, you may need to make some adjustments in Exposure & Shadows, or maybe tone down a color or two, which I have to do every time, regardless, because lighting is never exactly the same. But that literally takes a total of 5 seconds, so it's super easy, especially if you've been using Lightroom for a while and know how to use it.

• As you can see, the "Mirror Selfie" is not only used for my mirror selfies on instagram, but I also used it for the Christmas tree photo. I find that it's a good one to use when inside and when light is basically going against the object... meaning, there is not very good lighting, and the light is basically opposite of where I want it.
• "SoCal Love" is my favorite to use for beach photos, sunset photos, or fun, random ones I take directly in the sun. (95% of my photos are taken in the shade.)
• I'm not the biggest fan of yellow tones, so when there is a lot of it, I like to use "BFF." 
• "Home Sweet Home" is a newer one I've started to use, and I named it Home Sweet Home, because I've been loving it for home decor photos. Mainly in the living room. For this one, it does have "Vignetting," around the border, so I actually do turn that all the way down most of the time, but I liked it for the photo I used as my sample, and wanted you guys to have the option of it, but it can always be turned off under "effects" on your right hand sidebar towards the bottom.
• "Warmth" is exactly what it sounds like. It adds more warmth to your photo.
• "Pink Vibes" is a fun one. I like using it for outside selfie photos like my sample. The lighting there was outside at my bridal shower, which was at a restaurant with an awning over us, so it was like a partial outside/inside type of lighting.
• "Pastel" can be a little tricky with skin coloring. It was PERFECT for the photo sample I used, but when I use it for others, I play around with the "Luminance" for Orange, which can be found under "Colors" in your right hand sidebar.
