My first step in photo organisation is to take a quick look and delete the blurry photos (I will take 5-10 shots of the same thing and select the sharpest shot). To do this I need to view the photos at full size. But scrolling to a new photos resets the view size back out to show the whole photo. How can I scroll maintianing the current zoom setting, so as to not have to zoom in again for each photo.
