how to remove white status bar (or navigation panels) in photo app

Since I downloaded the new iOS7, the status bar (or navigation bars on top and bottom) in the photo app stays and is white. With the older OS version, it was black and disappeared after a couple of second. Now the white bar stays and you do not have a full view of the picture (top and bottom is cut off when holding it lengthwise) Any idea how to remove this? Thanks
