## Long description

KAISER format mask model 4491 is a precision metal mask sized 24.5×36.5 mm designed for use with 35 mm film frames in scanning, contact printing and darkroom enlarging. Manufactured to accurate dimensions, the mask provides consistent framing and reliable edge definition for prints and digital captures. Its metal construction offers durability and dimensional stability to maintain repeatable composition control during scanning or enlarging workflows.
Advantages
The metal film format mask delivers precise, repeatable framing without relying on variable paper or hand-cut guides. Its fixed rectangular opening ensures consistent crop and image borders across multiple frames, improving efficiency in batch scanning and contact printing. The robust metal build resists bending and warping, preserving the exact 24.5×36.5 mm aperture over extended use. The compact, flat design integrates easily into film holders, enlarger carriers and scanner accessories.
Suitable for
 35 mm film scanning with fixed crop requirements
 Contact printing and darkroom enlarging with consistent frame borders
 Archival reproduction and digitization of negatives
 Studio workflows requiring repeatable composition control
Key specifications
 Material: metal construction for dimensional stability
 Aperture size: 24.5 × 36.5 mm rectangular opening
 Intended film format: standard 35 mm film frames
 Form factor: flat, thin mask suitable for film holders and carriers
 Finish: manufactured to precise edge definition for clear borders
How to use
Place the metal mask into the film holder, scanner carrier or enlarger gate so that the 24.5×36.5 mm aperture aligns with the film frame. Ensure the film sits flat and is properly registered against the holder so that the mask edges define the visible image area. For scanning, adjust scanner preview to match the mask framing and lock settings before batch scanning. In the darkroom, position the mask in the enlarger gate and focus through the aperture; exposure tests can confirm final crop and edge clarity.
Usage recommendations
Handle the metal mask by its outer edges to avoid transferring oils to the aperture and keep the opening free of dust. Store flat in a protective sleeve when not in use to prevent scratches or deformation. For best results when digitizing or printing, perform a test frame to confirm alignment and exposure before processing a full roll.
