Luminar is an image editing program that works as a standalone application, or a plugin for Photoshop/Lightroom.
It offers a range of “creative filters”, allowing the user to create various stylisations. However, my editing style, if you can call it that, is very simple and rather conservative. See how I’ve used Luminar to develop RAW files from two recent shoots at different locations, using its basic tools. (Both exposed with Breakthrough Filters)
