It's an amazing piece of software for photographers. But does not work in Linux. That's a big issue for me, would not mind paying it at all.
It's way easier and faster to produce a vivid web-ready image with Luminar compared to my Lightroom Classic experience
Been using it for a while, and love seeing progress over last several months.
It's the must have product for photo lovers and professionals
Give it a try, works really great not only for drones, but for all kind of aerial, like rooftops, etc.
