After making edits to photos, we’ll likely want to export them so that they can be printed or shared online. When exporting photos, we can choose where they should be saved, if they should be renamed (and what the new names should be), what file type the images should be exported as, what size and resolution the images should be when exported, and more. We can export images one at a time, or select a number of images to export all at once.
What will your photo be used for after it’s exported?
Before exporting a photograph from Lightroom, you'll need to think about what your image will be used for before starting the export process. The image’s ultimate destination will have an impact on what export options you'll choose, such as the file format and resolution. If your image is being printed, you’ll need to choose different options than what you would if you export the image for screen use.
For the sake of time today, we won’t go too deeply into discussing file types and resolution — for a detailed discussion about image resolution and file types, view the page Understanding image resolution and file output from the IT Training course Photoshop: The Basics. For today, we’ll just touch on the file formats and basic values you’ll want to use based on where your photographs will be used.
If you’re planning on using the image on a website or sharing it on social media, the best file type for that is JPEG, with a resolution of 72 pixels per inch. If the image will be printed, you’ll want to export it as a TIFF file, with a resolution of at least 150 pixels per inch. (The higher the image’s resolution, the better the image’s quality will be when printed.)
Exporting a photo
We can start the export process in two different ways: if we’re in the Library module, we can click the Export button at the bottom of the left panel dock; we can also access the Export command from the File menu in the Menu bar. Both methods will bring you to the Export dialog box.
Let’s export the photo jack.dng as a JPEG file. We’ll export it with a resolution of 72 pixels per inch (or ppi) so it’s optimized for web use.
