Whats the easiest way to apply a profile to a large number of images in Lightroom?
First, select a set of images in your LR catalog. Next, choose your desired profile from the Profile popup menu in the Develop module’s Camera Calibration panel. Then choose “Sync Settings…” from the Settings menu. Make sure “Calibration” is checked in the ensuing dialog box and click Synchronize. If you find yourself doing this a lot, you can save yourself time by making a preset. In the Develop module’s left panel, click the + button to the right of the word “Presets”. Make sure “Calibration” is checked in the ensuing dialog box and click Create. Then whenever you need to apply your preset to a group of images, click on your newly-created preset from the Presets list in the left panel. You can also choose this preset in the Import dialog box to apply your desired camera profile to all imported images. Another way to apply a given profile automatically to all new images is to modify LR’s default settings for your camera.
