Yes. While assume not a Brownie (camera unknown but of that era) one of the two trays accepts the 2" wide 120 film. Length (square vs rectangle) doesn't matter as you can put a strip of two or three negatives in the guide on the platen. The padding on the lid lifts off exposing a light that shines through the negative (or slide) during the scan. The negative will be converted to a positive by the scanning software so no other software is required...but I do clean up with Photoshop. I personally gave up on the auto scan as it couldn't find the separation bar between the negatives, and selected the area, scanning individually. Also, while in Photoshop, while I preserved the original scan file, knowing intended print was 4x6, I cropped the exact area I wanted and saved them to a 4x6 crop folder for printing. If I wanted a 5x7 or 8x10, would go back to the original scan and do the same rather than letting printing software choose the composition for me..
