The Tiffen 4 x 5" #9 (3) Yellow Filter is a basic contrast filter, primarily for use with black and white film. This medium yellow filter slightly darkens skies, helps to cut through haze, and improves overall contrast. It is a common contrast filter for black and white photography, producing an accurate tonal range and compensating for the blue sensitivity of panchromatic film.

There is a 2x filter factor with this filter, requiring an increase of 1 stop for normal exposure. Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 10,000th of an inch. This filter measures 4 x 5" / 101.6 x 127mm.

Q: 7. Would I be able to warp it around a Canon F-1?

A: Ruggard 11 x 11" Padded Equipment Wrap (Black) will probably work on the Canon F1. I would recommend using a cloth napkin that you have at home and wrapping the camera with that. Checking which size worked well that allowed the napkin to go all around the camera and would allow the velcro at the ends to overlap over the wrap, keep the wrap tight and then checking which size worked and buy a wrap that offers that similar size.
