Negative Supply 6x4.5cm Single Frame ANR Mask for 4x5" Pro Film Carrier

This mask allows you to perfectly mask single negatives of 6x4.5cm film with our Pro Film Carrier 4x5. Simply replace the lower sheet of ANR from your Pro Film Carrier 4x5 with our Single Frame ANR Mask. No tools are required to switch your 4x5 glass out for a mask - just rotate our CNC machined thumb screws on your carrier, and switch easily and quickly to the desired mask.

Made from anodized, precision CNC machined 6061 series aluminum, these masks feature aerospace manufacturing tolerances with a razor thin machined aluminum framing window cut for a specific film size. Each mask features a custom cut and edge-smoothed piece of ANR (Anti Newton Ring) glass.

Film is held absolutely flat with these masks thanks to our unique and custom engineered floating hinge mechanism on our Pro Film Carrier 4x5, designed to auto adjust or manually be adjusted to compensate for the thickness of your film, ensuring absolute sharpness for every scan.

All of our single frame masks have a slightly larger opening than the single frame size itself, so as to assure a wide range of macro lenses can easily be used and to guarantee full border capability for each format.
