Presets are basically filters available for Adobe Lightroom. They are formulas that make your images look a certain way. Lightroom is a professional photo editing program that photographers use. They use Lightroom's software to create a certain look for their photos. The great thing about Lightroom is that the program allows you the possibility to change any of the colors in the image. These presets are all the presets i've ever used on my photos and yes, I only use Lightroom to edit/color my photos. Even though these Mobile presets are one simple click, you'll need to adjust the exposure, saturation, temperature and contrast to your fit your images and/or to match the settings of your camera.This is very normal( I still do it) and the more you use them and change settings you will start to develop your own look (presets) for your photos.
