3 free presets for people who like purples and blues! These can fit on whatever really, but they thrive on low light and blue hour style photos.  Grainy, pastels, colorful, and smooth I'd describe them as.  The photos in the cover are a good example of what low light and blue hour looks like, but of course all lighting conditions and image quality will vary.  
 
Things to note!!
 
Make sure if you're on iPhone only to download the dng files and import those 3 pics into lightroom.  So say you download them.  Go to files on your phone, click the zip, open the folder, click the dng pics, then click import and open them with lightroom.  Once they are imported and you have lightroom open, click the 3 dots at the top of the screen and click create preset. That's how you save them if you only have mobile.  You'll do that for all 3 presets. This will save the preset.  You can name it whatever you want since it'll ask, or just copy the name I had for them. :) It's annoying saving them this way but it takes no time.
 
Everything else should work great! Desktop will just take the xmp files and the samsung should have a quick and easy import option within lightroom already. So these other ways will just work on thier own, just iphone thats an extra minute.
