I like that the program goes as deep as you need it to go. From the basic adjustments like brightness and saturation, all the way to more complicated color replacement and advanced masking options. The organization and virtual image stacking help keep my photos organized without ending up with a bunch of duplicates on my hard drives taking up valuable space. It has been much easier to learn than photoshop and the integration with the phone app has been useful when I want to access a photo on the go.
I dislike that there isn't an option to integrate with Google Drive or Dropbox, Creative cloud is great, but most of my clients use the first two options and it would be a nice feature to have. The other main issue I have is that there isn't a very robust LUT management system, and I have to drag and drop individually to sort them into separate folders, which is a pain when I have a large LUT collection or am importing new LUT folders.
Lightroom is a great option for those who need to edit photos in a less complex way than Photoshop.
I have been able to form a cohesive photo look for all of our social media deliverables, including a color palette that is applied to all photos, which makes the Instagram feed look great. It has also been useful for developing LUTs for use in Adobe Premiere.
