If you haven’t checked out my post on “How to create your own presets in adobe lightroom” then I would recommend you checking it out before going through this post.
To import photos in Lightroom hit “CTRL+SHIFT+I”. The import window will open. On the top right hand side Click on “Apply during import” and select the preset you would like to apply to ALL photos during the import phase.
Click “Import” at the bottom right side of the screen. Lightroom will remember this setting once you have imported at least one picture.
