  • Low pass filters & The Red Monstro. What are they used for?

    Posted by matt patterson on October 26, 2022 at 6:43 pm

    Hi Guys

    Can some one help me? I don’t understand what low pass filters are used for in relation to the Red monstro camera? I looked through the forums but there isn’t a discussion that actually tells you what a low pass filter does in relation to cinematography and the monstro camera, there seems to be a lot of information regarding low pass filters and Audio.

    Thanks guys, would really appreciate help.

    In the RED MONSTRO camera, a low-pass filter is used to reduce moire and aliasing artifacts in the recorded images.

    Moire and aliasing are visual artifacts that can occur when a camera sensor captures patterns or fine details that exceed its resolving capability while shooting a video. These artifacts can create unwanted patterns or distortion in the image, especially when capturing certain types of fabrics, textures, or high-frequency patterns. A low-pass filter is designed to counteract these artifacts by slightly blurring the image before it reaches the camera sensor.
