The Collection includes 5 of my best Lr presets. I use them in 99% of the time and make slight tweaks to adapt to the different situations I am in. These Presets work with the free Lightroom Mobile version as well as Lightroom Desktop. They are simple to install and even easier to use. The Lr Preset works perfectly across pretty much any device you will shoot with. I think it’s perfect but, y’know, I’m biased.
