Quick Answer: How Do I Do Smart Previews in Lightroom?
Contents

To enable this feature go to the Performance tab in Preferences and tick the Use Smart Previews instead of Originals for image editing box. Then restart Lightroom to make it work. The idea is that working with Smart Previews enables you to work faster in the Develop module.

Where does Lightroom CC store smart previews?

Let me explain. When the Smart Previews feature is enabled, Lightroom generates a smaller version of your photo called a Smart Preview. This is a DNG compressed file that is 2550 pixels on the longest edge. Lightroom stores these DNG images next to the active catalog inside the folder with the Smart Previews.

Should you use smart previews?

When should you create Smart Previews? If you only ever edit your photos at home, and you always have the hard drive containing your Raw files to hand, there may be no need to build Smart Previews. It takes time for Lightroom to build them, and even though they are small, they do take up hard drive space.
