Camera Raw to Photoshop

It works if multiple images are selected in the filmstrip in Camera Raw. Any images selected in the filmstrip will be sent to Photoshop when you click the Open button.

To load multiple images into Camera Raw from Photoshop, choose File > Open, go to the folder or collection containing the images, select multiple raw images, and click Open.

To load multiple images into Camera Raw from Adobe Bridge, go to the folder or collection containing the images, select multiple images, and choose File > Open in Camera Raw.

I think you can also select multiple raw files on the desktop, then drag and drop them into Photoshop, and that should open Camera Raw with all of the images in the filmstrip.
