You can set all your pictures to the proper white balance and exposure with a few clicks. Insert an adjustment layer. Open the Image/Adjustment/Level dialog, clicking the black eyedrop to the black border of this panel in the picture, the gray eyedrop to the gray panel and the white eyedrop to the white part. This simple process set your picture to the proper exposure and white balance. One you have a correct layer, you can drag and drop this correct layer to the rest of the pictures. All the pictures will pick up the same consistency. This panel comes with its own carry case. It is 12" in diameter and can be folded down to 4".
