Auto advance is a great feature in Lightroom that lets you speed up the editing process by automatically adding new images to your photo library as you work. Auto advance can be set up on your computer or in Lightroom itself, and it can be used to add images from your camera roll, from online sources such as Flickr, or from any other source you might have access to. To set up auto advance in Lightroom, first open the photo editor and click on the Auto Advance button at the bottom of the main screen. You will then be able to select which sources of images you want to include in your auto advance. If you are using Lightroom on a computer, you will need to open a file browser and browse through your camera roll for images that meet the requirements for auto advance. Once you have found some good images, click on them and then click on the Auto Advance button at the bottom of the main screen. Once auto advance is set up, it will start working automatically and will add new images to your photo library as they are added. You can also control how often new images are added by changing the settings under Auto Advance > Add New Images Frequency.
