The Tiffen 4 x 5.65" CC20B Blue Filter is a color compensating (or color correction) filter for use when making color balance adjustments. It can be used to alter the color balance of a scene by placing in front of a light source or the lens of your camera. It can also be used to apply color corrections when used in the darkroom with an enlarger or to help pre-visualize color adjustments when viewing prints.

Blue is the opposite of yellow and can be used to reduce yellow tones or casts within a scene or print. This blue CC20 is more dense than a CC10 filter and less dense than a CC30 filter, and requires a 0.6 stop compensation for normal exposure results.

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 1/10,000th of an inch. This filter measures 4 x 5.65" / 101.6 x 143.5mm.

If by multiple exposures you mean multiple images overlaid on each other, then editing software is your solution. Otherwise, the frame rate is what it is. This is not the camera for high speed frame rates with corresponding autofocus; you need to get into DSLRs for that
