Adjust a Bunch of Images at Once?

First, select a bunch of images you want to edit in Adobe Bridge, then press Command-R (PC: Ctrl-R) to open them all in Camera Raw, and the images will appear in a filmstrip along the left side of the Camera Raw window. By default, you’ll only be editing whichever of those images in the filmstrip is currently selected, so if you want to edit them all, click on the icon to the right of the word Filmstrip at the top left, and choose Select All from the pop-up menu that appears (or just press Command-A [PC: Ctrl-A]). Now, click on the image in the filmstrip you want to work on, and any changes you make to this image (which Adobe calls “the most-selected image”) will be immediately applied to all your other selected images at the same time. It’s pretty much a “change one, it changes them all” type of edit, but it’s one of those things that can save loads of time, especially when changing things like exposure or white balance across a lot of images all at once. When you’re done, either click the Open Images button to open all the selected images in the filmstrip in Photoshop, or click the Done button to apply those changes without actually opening any of the images.
