what is a preset?
Presets are pre-made editing settings in Adobe Lightroom. They are created and saved to make your editing process faster and consistent.
Presets can be applied as a one-click edit to give you a signature look or you can start from there and make the adjustment to achieve the look you desire.
Presets can be created for desktop or mobile. There is a FREE version of Lightroom mobile that you can download from the Apps store and start applying these preset to your photo.
