This Roscoe 1/8 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

    # 3216 1/8 Blue CTB Color Conversion Gel Filter (20 x 24" Sheet) is rated 4.5 out of 5 by 4.
    Rated 5 out of 5 by from Perfect for softbox users. This is a must for softbox users. Using a color meter, I noticed that when using a softbox, the temperature of my flash output dropped by about 200 - 300 degrees. I cut this gel to size and clip it to the interior baffle of the softbox, and it brings the temperature back to the original temperature. Works like a charm. If you need more CC, you can double it.

    Rated 3 out of 5 by from These were FOLDED! I don't know if Rosco folded them (I doubt it) or if someone at B&H did it (more likely). Gels should never be folded. They should be rolled up. They probably couldn't find a box long enough to fit them rolled instead of folded. But that's no excuse for ruining the product.
