Today’s Question: How can I email someone an image from Lightroom Mobile that is full resolution?
Tim’s Quick Answer: You can share a full-resolution image from the Lightroom mobile app by using the “Largest available dimensions” setting for Dimension when using either the “Share” or “Export as” options.
More Detail: When you share an image from the Lightroom mobile app the default image size is 2,048 pixels on the long side. However, you can also specify custom dimensions or use the full resolution of the image being shared with the Dimensions setting.
To get started select the image you want to share and tap the Share button at the top-right of the Lightroom mobile app interface. The icon for the Share button shows a rectangle with an arrow pointing up from the top. If you’re going to select the “Share” option, you need to click the settings button to the far right of the Share button to bring up the settings. If you simply click the Share button, you’ll be sharing with the default settings. Note that tapping the “Export as” option will take you to the same settings that you have when tapping the settings button associated with the Share button.
After tapping the settings button you can adjust the settings for sharing, including the file type, pixel dimensions, and other options. In this case you would select the “Largest available dimensions” option. Keep in mind, however, that if you are sharing an image that was synchronized from Lightroom Classic the maximum pixel dimensions will be 2,550 pixels on the long edge, because that image will have been synchronized as a smart preview rather than the original file format. Tap the checkmark icon at the top-right of the screen and you’ll be prompted with the options for sharing the image, including via email.
