Combine images using Photoshop with Lightroom

Follow this cross-application workflow:

• Start in Lightroom, using Lightroom’s powerful search feature to find photos and its user-friendly photo editing controls to adjust the photos.
• Lightroom doesn’t include compositing features, but Photoshop has everything you need to combine images in ways that stretch the imagination. So if you want to make a collage, a blended composite, or any design that includes multiple photos, pass those photos from Lightroom to Photoshop.
• Use Lightroom’s Edit in Photoshop command to pass each photo from Lightroom to Photoshop. 
• In Photoshop, combine the photos into one layered document. 
• Apply a layer Blending Mode to the top layer to make a quick blended composite in Photoshop. 
• Click File > Save and File > Close.
• Quit Photoshop.
• Back in Lightroom you’ll find your original photos with any adjustments you added to them in Lightroom, along with the creative composite you crafted in Photoshop.
