Of course there are plenty of times when you don’t want to use a polarizing filter. This serene scene from the famous Hongcun village in China is a perfect example.

Never stack traditional screw-in filters on top of each other. If you do you'll be courting poor quality and the increased likelihood of vignetting noticeable as a darkening in the corners in your photo.

LED light engines use inorganic LED light-sources in place of a consumable lamp. Like laser light sources, LED light engines are also highly reliable and can offer up to 20,000 hours of use with no maintenance needed resulting in lower-cost operations. LED light sources are mercury-free and can power off and on quickly, even compared to laser light engines.

Although historically LED's light output was far less than lamp and laser-based projectors, things are changing. Developers of high-output LED lights, like OSRAM, Samsung, and others, have made remarkable strides in increasing the Lumens of the LED light engines. These next generation LED lights can generate up to 3500 lumens of light output.

The oldest projector light source still in use today, is the lamp. Metal halide and UHP (Ultra High Performance) are the two types of lamps most commonly used. Metal halide lamps use a combination of rare earth metal salts and mercury vapor to deliver light. Mercury lamps produced a really bright light but have a significant downside. Because of the mercury, there is a high cost of operation and there can be disposal issues.

I keep a B+W filter on my lens at all times. Usually it's a UV filter but, when its time to attach a polarizing filter, it's removed.

Also, lamps generate a lot of heat and thus require cooling, which requires more space, increasing the projector's size, number of cooling fans, and the amount of noise. Lamps have the shortest life span of all the lighting solutions available today and the simple act of turning the projector on and off diminishes the lamp's operating life.

Laser-based light engines are incredibly reliable, lasting anywhere from 20k to 30k hours, and are mostly maintenance-free. Chances are, you would need to replace the entire projector long before the laser light engine fails.

Wanting to utilize laser, hybrid, and LED as light sources make sense, especially since they're often rated for 20,000 hours and higher. These projectors also require virtually no maintenance. However, the total cost over the lifetime of a UHP lamp projector can't be beaten. Having to spend a little extra (likely less than $200) every few years might be worth it, depending on the application.

Types ofpolarizingfilters

Laser light engines are incredibly bright compared to lamps and most LED-based light systems, so they would typically be the best option for projecting on large surfaces. There are typically three types of laser-light engine designs used by today's projector manufacturers.

It's worth noting that a polarizing filter, as it's actually made of two pieces of grey glass, absorbs light. It works or it doesn't, depending on the direction of the light.

Discrete RGB laser light engines are considered to be the best projector light source available, but this performance comes at a price. Laser projectors tend to be physically larger than other types of projectors and are also very expensive. These systems offer the best brightness, so for installations requiring a huge projection screen, this would be the best solution.

Remembering to keep both the filter and the front element of your lens clean is, therefore, essential to extract the best quality from your lens.

When photographing light sources (i.e., street lamps, sunrise and sunset) a blooming or spreading of the light and a smearing of color can result with photos made with a dirty filter and/or lens.

It's just like wearing polarizing sunglasses on a bright day. If you or your subject is squinting it's probably a good day to employ the polarizing filter.

Using LED as a light source has been growing in popularity, mainly due to their small size, low heat, and affordability. Traditionally LED light engines are found in smaller, more portable projectors like a PICO projector. What PICO projectors lack in Lumens output is more than made up for in their size, power consumption, and portability. In some cases, PICO projectors can fit in a briefcase, purse, or even a pocket.

Business and education installations will value the performance and color accuracy of RGB LED-based light engines. These projectors are perfect for classroom and conference room type environments able to produce laser competitive colors, reliability, and, with the exception of brightness, do it at a lower price.

It's then simply a matter of turning the outside filter ring, while looking through the camera's viewfinder, until the desired effect is achieved.

The MRC coating also reduces internal reflections, between the filter and the front element of your lens, resulting in reduced occurrence of flare and ghosting in your photos.

This might allow you to photograph window displays or someone swimming under water without harsh reflections on the surface of the glass or water messing up your picture with irrelevant detail reflected form outside of the picture frame.

Made to the highest of standards, from arguably the world's best optical glass, it's worth considering filters that incorporate the B+W F-Pro filter mount.

There is a standard for determining a projector's brightness called ANSI Lumens. An ANSI Lumen rating uses an average of several brightness measurements taken across the face of the light source. The problem is there is no requirement for any manufacturer to use this specification.

While lamps are less expensive than LED or laser light sources, they are still an excellent light source. This is why they are still utilized in many higher-end home theater projectors from companies like JVC and Sony. Producing the same quality light as a bulb requires high-power RGB LED or multi-channel laser light source, which still commands a premium.

The degree of polarization that occurs is achieved by noting the outer glass element in relation to the inner element which remains fixed in place.

Most laser projectors utilize the least expensive solution, which is a single blue laser diode array that provides the blue light and excites a yellow phosphor color wheel. Filters are then used to break up the yellow into red and green elements.

I was captivated by the vibrant colors and intricate design of this beautiful flower inside the Flower Dome at the incredible Gardens by the Bay complex in Singapore.

So why would you recommend a lamp as a light source projector? It comes down to cost and light quality. As we mentioned, lamp-based systems are less expensive but have the shortest life. Lamps could be the choice if the projector is not being heavily used. For example, where the projector is only being used for an hour or two each day, the lamp's reduced initial hardware costs can make it a better value.

Polarizerfilter

In addition to much more accurate colors, because red, green, and blue light is produced by different lasers, a wider color gamut is also possible. Since the RGB laser wavelengths are specifically chosen to optimize the primary colors of red, green, and blue, a RGB laser projector has the ability to reproduce DCI-P3 or even the Rec. 2020 color gamut without the need for a color filter.

A polarizing filter is actually two pieces of glass sandwiched together. To use the filter simply screw the inside end securely onto the front of your lens.

The result, a thinner design that helps prevent vignetting, even on wide angle lenses, including most 24 mm focal lengths on full frame camera bodies.

The success of the photo is due, at least in part, to the reflections of the traditional village buildings in the water. Using a polarizing filter may well have reduced or even eliminated those reflections.

There are several benefits shared by all projectors that use lasers as a light source. First, laser-based light engines turn on within seconds of pressing the power button. There is no time wasted waiting for a lamp to warm up or cool down. Old mercury lamps can be damaged if unplugged before the cooling-down period ends.

So how many Lumens are right for your application? A good rule of thumb is if it's too bright you can turn it down, but you can't turn it up if it's not bright enough, at least not without sacrificing image size. So, the simple answer is, that depends. But to start with getting the brightest projector, for the budget, is a good place to start. Obviously, there will be other considerations like screen size, black levels, shadow detail, and color accuracy to name a few. All of this is determined by the intended use of the projector.

Just like laser light engines, LED light engines can and do have alternate configurations just as listed in hybrid laser light engines.

Polarizing filters are probably most commonly used to deepen (i.e., darken) the color of an already blue sky and, as a consequence, emphasize the shape and texture of clouds.

How do polarising filters work

As the price of better LED and laser light sources comes down, lamps will eventually be phased out. It's likely just a matter of time.

For higher brightness, some projectors use a dual blue laser light engine. One blue laser ultimately hits phosphor wheels to generate red and yellow beams, while the other blue laser handles the solely the blue component.

I know there are plenty of folks out there who leave their polarizing filter on all the time. The notion being that it’s there when they want it and the effects of the filter can be negated by spinning it until no change is visible through the camera’s viewfinder.

B+W filters are the best filters I have ever used. Made in German by Schneider I'm happy in the knowledge that, unlike cheaper plastic ringed filters, B+W filters won't lessen the quality of my high priced Sony lenses.

B+W filters incorporate a special Multi-Resistant Coating (MRC) which provides the filter with a water and dirt repelling coating.

Trying to determine what type of projector to use? The first thing you need to look at is the projector's Lumens. Lumens is an industry standard term that basically describes how much light a projector can put on screen and in turn, how bright the images appear on the screen. So how do you tell how bright a projector is? That can be a little complicated.

Today's projectors produce light in three different ways – lamps, lasers, and LED. In this article, we're going to take you through the advantages and disadvantages of each technology as well as help you understand which light source could better complement the environment that the projector is going to be installed.

The UHP lamp, created by Philips, was designed to be a more efficient alternative to metal halide lamps. They provide similar brightness with lower energy consumption and the UHP lamps produce a lot of light and are more affordable. The downside is their effective brightness degrades from day one, which means a UHP projector will never be as bright as the first time you turn it on.

Used correctly and under the right circumstances a polarizing filter can really make a difference to your success as a photographer.

Of course having two elements of grey glass in front of your camera’s lens will absorb light. Depending upon the circumstances that loss of light could, potentially, adversely effect your photo as follows:

B+W filters are made to last and are encased within a brass ring. This helps ensure that the filter won't become cross threaded if screwed on too tightly to your lens, a common and potentially expensive problem with cheaper filters utilizing plastic threads.

Starting in 2019, high Lumen, discrete RGB LED light engines are finding their way into projectors. Discrete RGB LEDs create red, green, and blue light. High-speed LED switching takes the place of the color and phosphor-wheels commonly found in DLP projectors to display each color at a frequency impossible to achieve mechanically. Since a wheel is not required, the noise produced is reduced and reliability is increased. RGB LED produces deeper, richer colors than comparable technologies for pure white reproduction and less DLP "rainbowing" (color breakup).

Polarizing filters can help to increase color saturation (i.e., the intensity or purity of a color) and maintain fine textures under conditions when bright light might otherwise cause color and texture to be reflected off the surface of the subject (e.g., wall, leaf, rock) and away from the lens.

When the filter’s not being used to polarize the light it’s still a barrier blocking light from reaching your camera’s sensor.

The best solution is to utilize multiple RGB lasers instead of a phosphor wheel and filters to create clean primary colors. Multi-channel laser light engines tend to produce a wider color gamut, making them a perfect choice for installations that require color accuracy in their displayed content.
