The Tiffen 2x2" Yellow Filter #9 (3)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 2 x 2" / 51 x 51mm.

Q: 7. Using flash outdoors (flash dialled 1 stop brighter than sun), id like to reduce the blue saturation of the ambient daylight (in a colour image, not B&W) will this filter reduce/mute/gray the blue saturation? If anyone has tried this, can you please direct me to an example image? Thanks everyone!

A: Colored filters are usually meant to be used to change the contrast in black and white photography. If you were to use a yellow filter while shooting color, the whole picture will have a yellow cast. The best way to reduce the blue saturation would be to either overexpose the sky, or ideally in post production you can under-saturate the blues.
