This Roscoe 3/4 Blue CTB Color Conversion Gel Filter is traditionally used to convert tungsten lighting to daylight. CTB (Color Temperature Blue) filters are available in a full spectrum of degrees (strengths) which, depending on your needs, can be used to either raise the temperature of your lighting or to create different lighting interpretations.

CTB filters offer you complete control when shooting under tungsten lighting.

    Rosco CTB Blue reviews

    # 3203 3/4 Blue CTB Color Conversion Gel Filter (20 x 24" Sheet) is rated 4.8 out of 5 by 5.
    Rated 5 out of 5 by from Do you have orange people? I recently took a position at a church as the Media/Tech Director. As with most churches, the equipment was mostly outdated and set up improperly. With little budget to speak of, I had to make an old truss full of Par64 cans work for our move into HD video. These gels saved the day! They turned a stage full of orange people into nice white, crisp color corrected goodness. We used a combination of 3/4 and Full Blue CTB gels to set us up for a slow transition to LED's over the next few years.

    Rated 4 out of 5 by from works, manufacturer should label the corners It works fine, but with all gels I really wish the manufacturer would print a simple label, 3/4 CTB, on all four corners as this is the first thing I do with all gels, its both time consuming and my sharpie penmanship is not as nice as a manufacture could make it

    Rated 5 out of 5 by from Always reliable Durable, good color. I throw this on a tungsten light to cool it but keep it warmer than daylight.
