Fixture for camera film scan

To scan old camera films is possible to use this fixture, where the source of the light is mobile phone screen. Some old films are biased in color so much, you cannot tune it in photo SW. So using proper application on you phone will help. If you cannot tune white balance (mostly is picture too blue) use backgroung blue light from app. I am using Screenlight. There is hole for clamp in order not to shuffle with fixture during film manipulation. The best is to use longest focal lenght lens possible with maximum aperture focused on film surface. Otherwise you can see display pixels in scanned photos.
