- (filter) 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 screen, plate, or layer of a substance that absorbs light or other radiation or selectively absorbs some of its components
- A device for suppressing electrical or sound waves of frequencies not required
- remove the dust from; "dust the cabinets"
- A fine powder
- Any material in the form of tiny particles
- Fine, dry powder consisting of tiny particles of earth or waste matter lying on the ground or on surfaces or carried in the air

Modern engineering combined with industry and shipping, and the backdrop of a sunset. The bridge is the medium cable-stayed Talmadge Memorial in Savannah, Ga.
The processing of this one is very simialar to an widescreen crop cityscape of Atlanta that I took a while back, where for the most part there isn't a lot of processing (mostly curves and levels here), but the sky is too delicate for normal sharpening (bad light rings), so the sky and non-sky areas have separate masked layers and are treated differently with regards to sharpening. The sky has a dust filter run on it to cut noise, that is it, the forground has heavier than normal sharpening applied (masking like this allows for much more as for the most part less noise is imparted and the objectionalble parts about oversharpening are eliminated with the masking system). However I did learn and do something new. This is a long range shot with my tele, enough so that darker (not black) areas showed a blue haze from the atmosphere (this is very noticeable in color landscapes of mountains). To eliminate this, I increased the contrast and slightly darkened (to counteract the high end increase, somewhat) the blue channel only. This had a very noticable and positive affect, and was much different than the results that one could expect from saturation and/or color balance. If you have a shot that suffers from long range blue haze (and it isn't an aerial which require much more intensive work), giving this a try could help out a lot.
You Never Know...
... when you'll need a gasmask and Domestic Preparedness filters
. Protects from pretty much all chemical particles and other nastyness; dust, bacteria, viruses, biological warfare agents, etc.
The list of examples speaks for itself: Sarin, mustard gas, phosgene, radioactive dust, anthrax, smallpox, ammonia, chlorine, hydrogen chloride, etc.
Smoke in a fire, not so much - carbon monoxide doesn't get filtered by a gas mask and in environments with less than 16% oxygen it's useless.
Still, it's a good make, lasts 15-odd years (filters
dated for 10+ years shelflife) and when the zombies eventually come after us, I won't be taking mine off, ever, for fear of contamination.
