Schneider 68-121044 overview

  • 1Description

The Schneider 4 x 4" True-Cut 750 IR Filter is an infrared control filter that is designed for digital cinematography. While recording video with a CCD or CMOS camera, multi-stop neutral-density filters are used to maintain proper exposure by compensating for increased light levels when widening the camera lens's iris to obtain a narrower depth of field. As the increased amount of light passes through multi-stop neutral-density filtration, visible light is progressively blocked, while infrared light is allowed to pass through. As the proportion of infrared light that reaches the sensor of a digital cinematography camera becomes greater, the results can show unwanted color shifts, particularly in dark areas of the frame such as shadows where the appearance of black is dominant.

When the Schneider 4 x 4" True-Cut 750 IR Filter is used along with multi-stop neutral-density filters while recording with a digital sensor, it blocks 50% of infrared light waves at 750 nanometers before progressively eliminating them. This helps to limit the light that falls on the sensor to the visible spectrum, preserving color accuracy throughout the frame as potential infrared color shifts are prevented or minimized. A similar True-Cut 680 IR filter moves the point at which 50% of light is blocked into the visible spectrum to 680 nanometers. While a True-Cut 750 IR filter is sufficient for many cameras, others may have sensors that require a higher degree of infrared control, such as that provided by a Schneider True-Cut 680 IR Filter.

Compatible with filter holders that can accommodate 4mm-thick, 4 x 4" rectangular filters.
Designed for use with CCD or CMOS sensors to filter out infrared light pollution that cause color shifts frequently associated with high-definition recording.
Ideal for use with multi-stop neutral-density filters.
Does not require adjustments to exposure while in use.
Constructed from water white glass for optical clarity.
Padded pouch for storage and transport.

    Schneider 68-121044 reviews

    4 x 4" True-Cut 750 IR Filter is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Fantastic filter... Well worth the cost. Never used a IR/UV cut filter before. I suspected my CCD equipped JVC GY-HM700U might be sensitive to IR polutiion.. I was right. In one take I noticed that the color and clarity was much better over not using it at all. This is a well made product and although looking through it with the naked eye it looks like a piece of clear glass, but it clearly blocked the ccd imager from the IR/UV polution.. Post editing reveiled the true result.. with the cut filter, clear nicely saturated HD content.. Stuff was there now that I never noticed prior to depolying the cut filter.. A must buy if you are out in brightly lit areas prone to UV and IR polution.. Works great in combination with ND gradiants..

    Rated 5 out of 5 by from A must have for any HD DSLR work Doesn't look like it does much until you colour correct your footage. It's a must have in front of your lens.
