Landscape presets are presets created specifically for landscape photos, giving the impression of high contrast.
Please remember that presets are a great base, but they will work differently on each photo depending on the lighting, colours, etc. To get the vibes you're wanting just right, start by adjusting the exposure, contrast, shadows, and colours such as oranges and yellows (as skin-tone varies from person to person).
1. Download the DNG files.
2. Import the DNG files into your Lightroom mobile app as you would any image.
3. Select the DNG image, tap on the 3 dots icon in the upper right corner and choose Copy dan Paste to your photo, or choose to Create Preset, to save the presets in your lightroom.
