White Balance Filters

White Balance Filters

White balance filters is a term used for digital cameras where filters already are built in. If you want to use a film camera you will need to have colored filters in front of your lens to achieve the right color scheme. The color diagram above shows which filter to choose to get rid of another. Use the circle’s opposite colors to find out which filters to use to absorb a certain color. For example: Use a cyan colored filter to absorb the reds in your images and a blue colored filter to absorb the yellow tones. The rules are the same as for white balance filters.

Star Filter

Without Star Filter                                                                                            Using Star Filter





On these two images, you can see the difference between using or not using a star filter in front of your camera.

White balance filters is a term used for digital cameras, Star Filters are great for adding that extra spark to pictures. It takes direct or reflected light sources and transforms them into glistening stars.

See below some examples of the different types of stars you can achieve by using a star filter. Star number 1 is the shape you’ll get when you’re using a Vector Star Filter, star number two is the shape of a North Star Filter star number three is the effect of a Hollywood Filter and last but not lease; Star number four which shape is called a Hyper Star.


Vector Star Filter                                                                                              North Star Filter









Hyper Star Filter                                                                                               Hollywood Star Filter









ND Filter

If you want to achieve blur and movement in a photograph when the light is strong using a slow shutter speed will result in an overexposure. In this situation you will need an ND filter, this makes your surroundings in the frame darker and you’ll be able to get the photograph you are wishing for.




Polarizing Filter

Polarizing Filters – The Best Camera Filter to Improve Your Landscape Images
By Rebecca Hiatt

Photographers often use polarizing filters to improve the appearance of the images they capture. With digital cameras, many filters are no longer necessary and do not always work correctly. There is one filter, however, that is the most often used filter, and it is considered a necessity to a landscape photographer. Whether using a digital or a film camera a polarizing filter will increase color and eliminate reflections in your images.

To unlock the secret of the polarizing filter, you must use the filter correctly.
To use your filter, find the correct size filter to fit the lens you are currently using. (a 55mm polarizer for a 55mm lens etc). Secondly, screw the filter onto the front end of the lens (nearest the subject). After the filter is snugly attached to the lens, rotate the filter. Look through the viewfinder as you rotate the filter and you will see the results immediately. Your landscape images will take on a whole new look; skies will become more deep blue, clouds more brilliant and grass greener. If you stand at a 90-degree angle to the sun you will get the maximum effect from your filter. Do not stand with the sun in front of you or behind you to take the shot.

A polarizing filter, used properly, on an overcast day will saturate the colors of the wet leaves giving life to the image. Of course, you must be very careful on a low light day as a filter can make your images too dark. A polarizer will cut the amount of light reaching your film or sensor. To counteract the decreased light reaching the sensor or film, open the aperture or slow your shutter speed to compensate.

Even though using a polarizing filter has many benefits, which far outweigh the pitfalls, there are several pitfalls of using a polarizing filter. Most of the pitfalls can be avoided with a bit of knowledge.

The first thing one needs to know about a polarizing filter is that there are 2 different types. One is the linear polarizing filter the other is the circular polarizing filter. A circular or a linear filter will do exactly the same thing for your images; enhance them. To compare them, the circular filter is more expensive and the linear filter may not be the best choice for most cameras that use autofocus.

A linear filter will often ruin the performance of autofocus; the camera is unable to transform the information correctly coming from the filter. A circular polarizing filter has an added layer which scrambles the filtered light coming from the polarizer and the camera is able to read the information more clearly.

The extra layer in the circular filter is the main reason the circular is more expensive. But as you can see it is often well worth the extra expense. Also, be sure when you purchase a filter that there is no color cast in the filter. Some filters come with an odd cast, green or yellowish color; make sure your filter has only a neutral grey cast.

Another problem encountered with polarizing filters is found when using wide-angle lenses (28mm or wider). A wide-angle lens may see the rim of your filter, causing a darkening at the edges of the image. Also, the sky can become unevenly polarized as polarization varies with the angle of the sun and a wide-angle lens covers a wider area of the sky.

Even with a few pitfalls, the results achieved with a circular polarizing filter are definitely well worth the price of the filter. Using a polarizing filter will take your images to a whole new level.

The Use of a Polarizing Filter
By Chin Yong Sak

There are many different types of filters available which serve different purposes aimed to enhance the effect of the photographs. There is a particular filter which you must have, in your camera kit bag and that is a polarizing filter.

Have you ever wonder how do some photos from the postcard, travel images, etc able to produce very nice deep blue sky? How do the photographers able to cut down the reflections on the subjects? The answer to this is by the use of a polarizing filter.

With this filter, you are able to cut down on the reflections which in turn produce a more saturated image which adds a special touch to your photographs. Although this effect can be easily achieved by using some photo editing software, but its still worth getting a polarizing filter for a quick and immediate effect.

The polarizing filter can be easily attached to the front of your lens simply by screwing it in (in most cases). There is another ring (normally the outer ring of the filter) where you can rotate it 360°. Look through the viewfinder while rotating the ring and you will be able to notice the change in effect the filter produced.

You can do a simple experience with the filter and your camera. With the filter attached, point your camera to the blue sky. Look through the viewfinder and observe carefully at the blue sky as you rotate the outer ring. Did you notice that the blue sky will get darker and darker and as you keep rotating the ring, the color of sky gets lighter and even back to the original color?

Generally, the polarizing filter is most effective when the sun is 90° angle to your subject. The filter will have minimal or no effect when the sun is directly behind your main subject. So with this illustrates, hopefully, you will be able to understand the relationship between the polarizing effects with respect to the sun position to your main subject.

The polarizing filter can be used when shooting clear, still water during daytime. It can help by cutting down the reflections on the water and you are able to “see” into the water. The same explanation can be applied to shooting reflective surface, example leaves, foliage, etc to achieve nice saturated color.

Although this filter is able to produce a more saturated effect on your image, do be careful not to over-do it. This will result in your photographs having unnatural color, which is not too appealing to landscape photographer (unless you want to effect deliberately). Normally, what most photographers do is they rotate the ring of the filter to achieve maximum effect, and which that, they go back slightly by a few degrees to get the best effect.

There are mainly 2 types of polarizing filter namely linear and circular. As technology advance, most SLR today are digital in nature with auto-focus ability. Thus a circular polarizer is widely used for cameras has a through-the-lens metering system and/or auto-focus.

Hopefully, with the explanations above, you will be able to understand the use and the importance of having a polarizing filter. There is an old saying, “Practice Make Perfect”. Do take more outdoor shots and appreciate the use of a polarizing filter.
