 This becomes even more important when you need to crop or digitally straighten photos.
-There are smaller films such as 110 (13x17mm frame size, 2,047 by 2,677 pixels) and larger films such as medium format (60x60mm, 9,448 by 9,448 pixels) so **you may need to adjust the DPI setting, especially for professional photos**. But for the most part, when scanning old photographs, **try to keep the long edge at least 5,000 pixels**.
