All Scales Show Both Horizontal and Vertical values
    Each  Film Scale shows 9-10 of the most commonly used lenses.
The Video Zooms  show  5 of the most commonly used Canon & Angènieux Zooms.
    Fantastic for finding Translite, Blue Screen, & Backing sizes, locating ceiling pieces, cutters, matte lines, camera placement , the list is endless.
    Great care was taken to maintain the highest accuracy.
    The 35mm. Lens Angles were taken from The American Cinematorapher's Manual,
    Canon Tables supplied the data for the TV Zooms,
and IMAX field angle tables were complied from their "IMAX Corp. Design Facts". 
    All CAD drawings were made at TEN TIMES ACTUAL SIZE.
Then each lens value was magnified by a factor of TEN TIMES. Giving an accuracy of Four Decimal Places, on the "Minute of an Angle"
