LEE Filters - 201 full CTB, pro rata

The LEE Filters 201 Full CTB filter stands as an indispensable tool for professional cinematographers, photographers, and lighting designers seeking to meticulously control and correct color temperature in their lighting setups. Engineered to precisely convert tungsten light sources (typically 3200K) to a daylight equivalent (approximately 5500K-6000K), this filter ensures consistent and accurate color rendition across a multitude of production environments. Its partial nature, denoted by "anteilig," implies it's often available in specific cuts or lengths suitable for individual fixtures, offering both flexibility and cost-efficiency for various applications, from studio work to on-location shoots where ambient daylight is a primary concern. The filter's consistent color correction capabilities are paramount for achieving natural-looking skin tones and vibrant, true-to-life colors, thereby elevating the overall production quality.

COLOR CORRECTION AND APPLICATION
Function: The 201 Full CTB (Color Temperature Blue) filter is specifically designed to raise the color temperature of incandescent or tungsten light sources. By adding a significant blue hue, it effectively transforms warmer light into a cooler, daylight-balanced output.
Correction Strength: A "full" CTB denotes its strong color correction capability, making it ideal for situations requiring substantial color temperature adjustment, typically converting 3200K tungsten to a nominal 5500K-6000K daylight.
Primary Use Cases: Essential for balancing interior tungsten lighting with natural daylight entering through windows, or for matching studio tungsten fixtures with daylight-balanced HMI or LED lights. It is also frequently used to simulate daylight in artificial environments or to achieve specific aesthetic looks.
Color Rendition: Ensures that subjects and scenes appear natural and accurately colored when viewed or recorded under mixed lighting conditions, preventing an unwanted orange cast from tungsten sources.

LIGHT TRANSMISSION AND DENSITY
Light Loss: As with all color correction filters, the 201 Full CTB inherently causes some light loss due to its dense coloration. Users should account for this light reduction when planning their lighting setup and exposure.
Density: The specific density of a full CTB filter is calibrated for maximum color shift, meaning it will absorb a significant portion of the light spectrum. This light loss is a necessary trade-off for achieving the desired color transformation.
Consistency: LEE Filters are renowned for their consistent density and color across the entire sheet, ensuring uniform correction regardless of the filter's position on the light source.

MATERIAL QUALITY AND DURABILITY
Material Composition: Crafted from high-quality, heat-resistant polyester material that is robust enough to withstand the thermal demands of professional lighting fixtures. This ensures the filter maintains its integrity and color stability over extended periods of use.
Heat Resistance: Engineered to endure the high temperatures generated by various light sources, preventing warping, melting, or color degradation that could compromise its performance or longevity.
Optical Clarity: Manufactured to the highest optical standards, ensuring no compromise to light purity or image quality. The filter is free from imperfections that could introduce artifacts or distortions into the light beam.
Longevity: Designed for repeated professional use, offering consistent performance and durability even in demanding production environments. Proper handling and storage further extend its operational lifespan.

FORMAT AND HANDLING
Format: The "anteilig" designation indicates that this product is typically supplied in pre-cut sheets or rolls of specific lengths, allowing users to precisely cut the required size for individual fixtures, barn doors, or diffusion frames. This offers flexibility and minimizes material waste.
Ease of Use: The material is easy to cut, shape, and attach to lighting equipment using standard gaffer tape, clips, or frames. Its flexible nature allows for adaptation to various light shapes and sizes.
Storage: For optimal preservation of its optical properties and longevity, the filter should be stored flat, away from direct sunlight, extreme temperatures, and abrasive surfaces.

CLASSIFICATION
The LEE Filters 201 Full CTB (Color Temperature Blue) filter is classified as a professional-grade color correction gel within the realm of motion picture, television, and still photography lighting. It specifically falls under the category of color temperature conversion filters, designed to dramatically adjust the Kelvin temperature of artificial light sources. Its "full" designation places it at the higher end of the CTB spectrum, signifying its robust capability to transform warmer light (e.g., 3200K tungsten) into a simulated daylight output (around 5500K-6000K). As a primary tool for lighting technicians, cinematographers, and photographers, this filter addresses critical color balancing needs, enabling precise control over the aesthetic and technical aspects of visual storytelling. Its partial availability, suggested by "anteilig," further classifies it as a versatile and adaptable consumable for production, allowing for customized application to a wide array of lighting fixtures. Its high-quality polyester construction, excellent heat resistance, and consistent optical performance firmly establish it as a premium choice for achieving accurate and consistent color rendition in complex lighting scenarios, from studio setups to challenging outdoor shoots.
