Description
A cheaper alternative to the Instax 210, the Polaroid 545i is operated manually. A sheet of Instax Wide film goes under the transparency taped to the 4×5 dark slide; with the 545i unlocked, the dark slide / film combo is inserted into the holder. The holder is locked and the user (slowly and evenly) pulls the 4×5 dark slide out.
Please note that this is an experimental method of developing Instax Wide film and may produce uneven and unexpected results. No guarantees are made as to how consistent development will be with this holder.
Use at your own risk.
