- A screen, plate, or layer of a substance that absorbs light or other radiation or selectively absorbs some of its components
- device that removes something from whatever passes through it
- an electrical device that alters the frequency spectrum of signals passing through it
- remove by passing through a filter; "filter out the impurities"
- A porous device for removing impurities or solid particles from a liquid or gas passed through it
- A device for suppressing electrical or sound waves of frequencies not required

From 26A
The view from seat 26A on the way into Brisbane. There was a light haze and soft light from the low-ish cloud, but enough light coming through to reflect off the water. Shot with a circular polarising filter, converted to black and white, levels tweaked and some games with layers.
