Graduated screens - The metric (1mm increment) and imperial (1/16" increment) scales allow you to easily mark smaller formats such as roll film holders, reducing backs, panoramic backs, internally reduced plate/film holders, and instant film backs. You can also create your own custom gridlines or simply use the (imperial) edge markings to level the horizon.
Usage: Use a foam backed ruler and marker pen to draw a line between your desired measurements on the scale on the smooth printed side of the glass. Use a marker such as a Uni Super Ink Marker (PNA-125). Remove your markings using rubbing alcohol with a soft cloth or cotton bud.
