Photographic Wet Printing Test Strip Mask 5x4 inch with 5 lift up masks, Biodegradable Plastic
The Film Bloke
This mask is used to make test strips on traditional photographic darkroom paper to determine the correct final exposure or to determine areas that need dodging or burning.
Original Design by The Film Bloke and 3D Printed made from Biodegradable PLA, a Hard and sturdy Bio Plastic made from vegetable matter such as corn husks etc. It biodegrades over about 6 months when left out in the open.
It has a 5mm Stainless Steel Hinge and lock nuts. Each individual Mask (5) overlaps the previous one, so exposures start from the left and progress toward the right end. Each strip has a little handle at the end with a raised 'bump' for gripping with the fingers.
The frame covers 1/4 sheet of 10x8 paper or a piece 5x4 inches.
