Unlike an infrared filter, a low-pass filter operates on high-frequency spatial information, whereas an infrared filter removes spectral information. To put it simply, the optical low pass filter slightly blurs out the image before it reaches the silicon sensor. In an age where camera reviews a...

All my modified DSLRs have their AA filter removed, according to the vendors who did the modification for me. Unfortunately I never had a chance to compare the images before/after the mod, since pretty much the first thing I did to a camera is to modify it. On Canon 5D2 (6.4um pixel...
光学低通滤波器(Optical Low Pass Filter,简称OLPF)实际是一低通滤波的石英作的晶片。1988年日本富士公司与东芝公司合作推出第一台数位静态相机(Digital Still Camera,简称DSC)起,才将OLPF带入这发展迅速的数位世界中。 数位影象技术如火箭般飞快地进步,应用的领域也日益宽广,从数码相机(DSC)、数位摄像机(DVC)到影...
