Updated 04-18-2023 — There are two new options for managing external editors and opening multiple images from Lightroom Classic into Photoshop.
- To select the version of Photoshop that you want to set as your default editor, choose Preference > External Editing. In the Edit In Photoshop section, choose the version of Photoshop that you want to be the default. This will be helpful for those needing to work with multiple versions of Photoshop for different projects (including the Photoshop Beta). Note: the default editor is what will be used when using the shortcut Command + E (Mac) | Control +E (Win).
- To quickly open files into another version of Photoshop, choose Preference > External Editing, and use the Additional External Editor section to choose another version of Photoshop as the applicatio. Then, use the Preset drop down to save the current settings as a new preset. Additional External Editor presets appear in the Photo > Edit In menu as well as the context sensitive menus, making it easy to choose between different applications.
- To open multiple files from Lightroom Classic into a single document in Photoshop as layered Smart Objects, select the desired files and choose Photo > Edit In > Open as Smart Object Layers in Photoshop.
