Providing us with your preferred preset(s) is super easy!
Within your account under 'Preferences' you'll see towards the bottom the Preset section. There you can upload the .lrtemplate file(s) and list where you would like it to be applied.
For example "Color preset for ceremony images only" or "Color preset for all images"
Please note that presets are only file type: .lrtemplate. If you are unsure of how to find this file you can easily do it within Lightroom. In Develop mode find your preset and right click the file. Hit 'Export'
A menu will appear and you can tell Lightroom where to save the file. The location you picked will then show the file (.lrtemplate).
