I find that the “out of the box” (so to speak) settings in Lightroom Classic’s preferences are a good place to start, but there are a few settings I find helpful to tweak. To access the preferences, go to Lightroom Classic > Preferences (PC: Edit > Preferences). The first tab up is General.
The main benefit of this setting is that when enabled you’ll see both the JPG and the raw file next to each other after import. When left unchecked you never see the JPG, which is fine, but at some point I tend to go back and delete the old JPG versions and you can’t do that if you can’t see them, which means you end up with a bunch of useless JPGs sitting in the source folder forever.
Moving over to the Presets tab, I also like to leave Show Partially Compatible Develop Presets checked.
The third is over on the Interface tab of the preferences. In the Filmstrip section, I like to enable the Ignore clicks on badges option. This only affects the badges that appear on thumbnails in the Filmstrip. I like seeing the badges as I find them helpful shortcuts to know what has been done to the photos, but with the filmstrip being rather small it is easy to inadvertently click one and end up in the Crop tool or Map module if you’re not careful. Disabling them acting as clickable buttons solves that problem, but you can still click them like buttons in Grid view of Library.
