What is a Low-Pass Filter? - Photography Life
- https://photographylife.com/what-is-low-pass-filter
- A low-pass filter, also known as anti-aliasing or blur filter, was designed by camera manufacturers to eliminate the problem of moiré by blurring what actually reaches the sensor. While extreme details are lost in the process, the problem of moiré is completely resolved. Since most cam…
What Is a Low Pass Filter and How Is It Used in Photography?
- https://shuttermuse.com/glossary/low-pass-filter/
- A low pass filter, also known as an ‘anti-aliasing’ filter or a ‘blur filter’ is a filter used by camera manufacturers to combat the effects of moiré in photographs. Moiré is caused when a a scene contains closely spaced repeating patterns, camera manufacturers combat this phenomenon by limiting the amount of light that is allowed into the camera, thus reducing the detail recorded in …

- The role of a low pass filter is to limit the frequency at which it is able to transmit lightwaves. It lets the lowest-frequency waves through and cuts off the highest, effectively reducing the amount of detail let through to the sensor.
The Low-Pass Filter - Digital Photo Magazine
- https://www.dpmag.com/cameras/slrs/the-low-pass-filter/
- The low-pass filter blurs the image’s high frequencies (fine detail) at the pixel level. This eliminates (or at least greatly reduces) moiré and artifacts—but it also reduces resolution. Medium-format photographers want maximum sharpness, and prefer to compensate for any moiré and artifacts on a per-image basis in postprocessing.

- A low-pass filter comprises several layers of optical quartz that have been cemented together and placed in front of a camera's sensor. They were put there to help prevent the appearance of moiré in images, or that odd effect when anything with a close pattern, for example ties or denim, would appear to be swirling and fuzzing, almost like the screen of an …

How to Use a Low Pass (Anti-Aliasing) Filter in Photography
- https://www.lightstalking.com/low-pass-anti-aliasing-filter/
- If you’re not an absolute beginner in photography, you’ve probably heard about low pass or anti-aliasing filters. This type of optical filter is also known as anti-aliasing or blur filter and it was designed by camera manufacturers to eliminate the problem of moiré (wavy patterns with repetitive details that exceed sensor resolution.)
No Low-Pass Filter on Photography Cameras - Outdoor …

- An AA filter, aka OLPF (optical low-pass filter), sits over the image sensor and does away with aliasing—artifacts and moiré that occur when you sample the real world with a fine grid of pixels. Conventional Bayer image sensors add color moiré to the mix, since each pixel “sees” only red, green or blue.

- Cameras with low-pass filters create images that are softer than they otherwise could be; cameras without low-pass filters create images that sometimes exhibit moiré or other artifacts. Fujifilm’s recently introduced X-Pro1 camera takes many design cues from classic rangefinder cameras but also includes a cutting-edge X-Trans CMOS sensor which omits the …
