UV, Haze, or Skylight?
Those who have read my other tips know I'm not a fan of using so called "protective" filters unless there is an overriding reason to do so such as when shooting around blowing sand or salt water.
UV, Haze & Skylight filters

HAZE - An atmospheric condition characterized by fine particles of dust, smoke or moisture in the air that causes a loss of contrast in an image because the haze scatters light particles.
haze
(1) residue of ink and/or stencil material remaining in a screen following stencil removal; (2) undesired cloudiness found in transparent areas of film, or base substrate.
HCS
acroynm for Hazardous Communication Standard (US).
Haze, Ultraviolet, UV, Skylight Filters
Film, unlike the human eye, is sensitive to some UV which adds blue and reduces visibility on distant landscapes. These filters should not be confused with Fog Filters, which are supposed to add "Fog.
UV Haze Filter: A visually clear filter that removes bluish haze caused by ultraviolet light. Commonly left on the lens all the time to serve as protection.
haze filter includes contrast and correction filters. When contrast and correction filters are used for haze penetration, they may be considered special-purpose filters.
Haze:
Atmospheric condition caused by fine particles of dust, smoke or moisture in the air. This causes loss of contrast in an image because of light scattering and general degradation of background image quality

A "UV haze" filter, appropriately sized to fit the front of your lens, can be useful if you're taking pictures in a dusty or wet environment or if you're lending your camera to a careless person.
Reducing haze. Since light comes from all over, at random polarizations, adding a polarizing filter will block the crossing polarization patterns of scattered and reflected light to reduce haze.
Removing reflections.
The Tiffen Haze-1 is best. It's a neutral filter so color balance is unaffected.
Next is the Tiffen 812. Good UV blocking if you also want a warming filter
The Hoya 81B warming filter is quite similar to the Tiffen 812.
Reducing Haze
These next two shots, shot on the same gray, rainy day as the previous pictures, show how a polarizer can improve landscapes in even the worst of weather.
HIE was useful for haze penetration and special effects in commercial, architectural, fine art, and landscape photography and was a wonderful film--so naturally it was discontinued at the end of 2007.
Polarizing filters will also lessen the noticeable effect of water vapor and particulate matter haze. The image may appear clearer and sharper when you've cut down the sun's reflections off the haze.
Aerial perspective: The feeling of depth created by haze. Distant objects are recorded with lighter zones and colors distorted toward blue.
Agitation: The method used to keep chemicals in contact with photographic materials during processing.
They cut down haze or blueness at the beach or in the mountains.
The 81-series warm-up and Soft focus filters can be used to create romantic portraits or landscapes.
I had already used a circular polarizing filter to cut through the haze and bring out detail. The Mountain was barely visible with the naked eye and would have been completely invisible with a small Digicam without a filter.
Fog, mist, smoke and haze can all act as an excellent natural filter.
Ethan Welty shot this with a Canon EOS 40D and 17-55mm f/2.8L Canon zoom. Exposure: 1/125 sec at f/5.6, ISO 200.
As limited in reducing haze as it may be, most photographers still insist on buying a UV filter as a lens protector. It can be a very practical lens protector since it does not influence or distort the pictures.
A warm mid-day haze adds to the feeling of the photograph and mutes the colors of the leaves and the hillside behind, while creating bright highlights on the river at the bottom of the scene.
After an all night rain, the dawn broke with a light haze and bright overcast, perfect photography weather. I took off down The Path, returning by way of Leggs Hill, drawn on by the wonderful light.
UV filters, on the other hand, pass visible light but filter out ultraviolet energy of a certain range, and so are good for cutting through same haze in landscape shots.
Their real use is attempting to reduce any haze that strong scattering of UV light may cause. The skylight filter is essentially a UV filter with a slight pink tinge in the glass.
A diffusion filter (also called a softening filter) softens subjects and generates a dreamy haze (see photon diffusion). This is most often used for portraits.
One problem you will encounter at high altitudes is an excess of ultraviolet light, which results in atmospheric haze. You can use this haze to advantage, but if it is obscuring your subject, you may need to place a filter over your DSLR lens.
The initial levels adjustment to cut through the haze/glare will have worked on the darker areas of the image. However, this left the highlights on the tops of the animals even further overexposed. One way to adjust this is to use the burn tool.
Many landscape photographers avoid the use of any filter other than a polarizer and perhaps a haze filter. Others use an arsenal of different filters to enhance the natural appearance of a scene.
A filter which is used in front of the lens in order to filter out UV light that can cause a blueish haze.
A UV filter is designed to reduce haze, caused by UV light, when shooting outdoors.
Aerial perspective uses atmospheric haze and light to convey depth. As the distance between an object and the viewer increases, the contrast of the object decreases.
Working distances tend to be short with underwater nude photography as distortion, haze, light falloff all increase dramatically with distance.
Bokeh is from a Japanese word for "blur" or "haze". It is a little bit of photographic trickery that can be lots of fun to do! This article will explain the basics of it. Feel free to improve upon the design or concept! ...
It also enhances colors and reduces haze. Polarizing filters are very useful when taking photographs in doors.
If the sky has the right amount of haze, the second type of magic hour #2 light may occur. In this case the light is as follows:
Color: Depending on conditions, the light can be either cool or warm.
Quality: The light is soft.
Aerial perspective - the distance or depth effect caused by atmospheric haze. Haze creates a large amount of extraneous ultra-violet light to which all photographic emulsions are sensitive.
Bringing back the old IR look with its haze and grain can be accomplished in Photoshop with some trial and error. The main tools will be an added layer with blur and the addition of grain.
Thanks, Kev. Um... heat haze... yeah... that's EXACTLY what I was going for.
To be completely honest, it was so cold I couldn't feel my hands!

The contrast deterioration is visible by a more a less severe haze so colors appear to be washed out. Ghostings can be either multiple images of strong light sources or aperture shaped light blobs due to inner reflections.
UV filter
A colourless filter thats used to absorb UV light and reduce haze when shooting with black & white film. A filter which is used to absorb ultraviolet (UV) radiation
Search SWPP and BPPA ...
The reflected light from lens elements that appears as a non-uniform haze or as bright spots on the film. This usually happens when a bright light directly enters the lens.
flash card: ...
Skylight filter
A UV filter with a pale rose tinge to it eliminate a blue colour cast caused by haze, it may be kept in place permanently to protect the lens from dust and scratching.
Intensifies blue skies.
Eliminates glare thus enhancing colour saturation.
Cuts down reflections off water and glass.
Helps cut through haze.
Absorbs between one and two f/stops of light so can be used as a neutral density filter.
Well, as the firework show progresses, the smoke will start to linger and create a haze over the nice dark background that you were using. By being at a right angle, the smoke will be blown out of your view faster.
Natural density: Waterfalls, rivers under bright light
Graduated neutral density: Dramatically lit landscapes
UV/haze: Improved clarity in any situation
Warming/cooling: Landscapes, underwater, special lighting ...
All kinds of dust and vapour in the air render the distance more vague. Especially fog and haze transform a landscape into a children's viewing box, where each next 'cut out layer' is painted in more dimmed hues.
This can result in flare problems and an overall haze. To be safe, zoom your flash head as much as possible (105mm on Canon) to create a narrow beam of light that hits your target(s), but not your lens.
A Band of wavelengths within the electromagnetic spectrum invisible to the human eye which are shorter than the blue end of the spectrum. All films are sensitive to some ultraviolet radiation. It shows as increased haze, ...
All kidding aside, your other option is to wait for the rain to stop. This, too, can be very effective; particularly when you want a still reflection. As well, rainfall can has a tendency to scrub haze and pollution from the atmosphere, ...
Because of this a polarising filter can do two things: remove white haze from the sky rendering it a deep blue, and remove white reflections from surfaces revealing their true colour.
Red filters will darken the sky, creating a moody atmosphere.
Green colored filters are particularly useful for landscapes, as they create a contrast between different shades of green.
Blue filters are effective for haze or misty conditions.
of birds or other flighted subjects blanketing their shadows on the ground. The stronger the light, the deeper the shadow. It stands to reason that the best shadow images using the sun as a light source are made on cloudless, pollution, and haze free ...
