Colour Look Up Tables (LUTs) are a brilliant way of colour grading your images in Photoshop, adding mood, atmosphere and your own style, but what if you do more in Lightroom, or Lightroom is all you use; can you still use them? The short answer is yes. They do need to be installed first, though, and although it's a simple process, it isn't just a case of clicking an install button. There are a few steps involved as well as a hidden keyboard shortcut, and this video goes through how to install, use and manage them. For Lightroom (Cloud), you need to navigate to the folder where Camera Raw has previously stored your LUTs. On a Mac that's ~/Library/Application Support/Adobe/CameraRaw/Settings, and on Windows it's C:\Users\[user name]\AppData\Roaming\Adobe\CameraRaw\Settings.
