Filter, low-pass

EN: Filter, low-pass

In a dSLR, one or more low-pass filters are located in front of the imaging sensor to:- allow the lowest-frequency waves through and cut off the highest, effectively reducing the amount of detail getting through to the sensor,- resolve aliasing that causes jagged edges when photographing circular objects and diagonal lines, and- protect the sensor from dust. Most have an anti-static coating to discourage dust from sticking.
