Those are nice tips! I have 4 116 folders I use fairly regularly. You can still get great results from using snipped plastic wall anchors which will fit into the ends of a 120 spool and then that spool will fit nicely in a camera like the Kodak 1A Autographic Special. The key for sharpness is a good lens but also film flatness so I do not advance to the next frame until I'm ready to take the next shot.

Some 116 folders (like the Kodak 1A Pocket) have a flat spring loaded back which helps to keep the film flat.

The color shot is from a Kodak 1A Autographic Special, the black and white (with selected focus) is from a Kodak 1A Pocket with the spring loaded back.
