The real secret to building slideshows with Adobe Photoshop Lightroom is in learning how Collections work and then mastering Lightroom’s hidden Set as Target Collection feature. You need these skills so that you can quickly gather together all of the images that you want to display in your slideshow. You will also need to put your images into a Collection before you enter the Slideshow Module if you want to arrange them into a logical order.
Building the slideshow is super easy once you have all of the images that you want to display arranged together within a single Collection. Lightroom’s Slideshow Module makes it easy to set the look and feel of the slideshow, to add in a soundtrack, and then to save the results out as a video file. That Lightroom can render your slideshow out as an .mp4 video file is a tremendous blessing.
Rendering your slideshow out as a video is a huge plus. When your finished product is a video, you can easily watch your slideshow on any mobile device or you could share your work by uploading this file to YouTube, Vimeo, Facebook, etc. The magic here is that you can go from a Collection of images in your Lightroom Catalog to a video file that anyone can watch on their own computer in almost no time!
