Why Does Infrared<\/keyword> Appear Purple in Digital Cameras?<\/h1>\n\n\n\n

The reason that infrared<\/a> sometimes appears purple on a camera’s monitor can be explained by an internal part of the camera. <\/p>\n\n\n\n

This is usually fixed by the manufacturer, and for most models there’s nothing you can do to correct the problem. <\/p>\n\n\n\n

On the other hand, if the monitor is a recent model then you might have noticed that there is a purple hue to the display. <\/p>\n\n\n\n

This is caused by an internal pixel of your camera that is operating poorly, or perhaps it’s just old.<\/p>\n\n\n\n

\"Why<\/figure>\n\n\n\n

If you want to fix this problem with your camera, the first thing you should try to do is to check the camera’s IR filter. <\/p>\n\n\n\n

An IR filter is a little rubber ring on the front side of your camera. <\/p>\n\n\n\n

If the camera doesn’t see the pattern it expects, it will try to detect the pattern by the infrared<\/keyword> rays, which it then processes as normal light<\/keyword>. <\/p>\n\n\n\n

If the infrared rays<\/a> are distorted or they don’t come through as expected, the camera will detect this and it will display a purple haze on the monitor.<\/p>\n\n\n\n

To solve this problem, the first thing that you should do is to check the IR filter on your computer. <\/p>\n\n\n\n

The easiest way to do this is to connect your computer to your printer, and then scan your printer with the appropriate cable. <\/p>\n\n\n\n

If the printer reports that there is no infrared<\/keyword> light<\/keyword> coming through, then there’s nothing wrong with your computer’s IR filter – all printers handle IR filters in a similar fashion. <\/p>\n\n\n\n

You can then go and check the internal pixel on your camera, and if it’s out of whack, you can simply replace it with a new one. The good news is that most cameras come with a generic replacement for this part.<\/p>\n\n\n\n

How the Purple Light<\/keyword> Will Excite Red and Blue Sensors Equally<\/h2>\n\n\n\n

A new technology has been introduced for the cameras, which is known as digital camera laser light<\/keyword>. The digital cameras will be able to work very well with these cameras. <\/p>\n\n\n\n

It will be able to use both of the sensors as they are all sensitive to light<\/keyword>. <\/p>\n\n\n\n

This type of camera has a color filter that is made up of four filters in them. The red, blue and green filters will have different intensities depending on what their sensor is detecting.<\/p>\n\n\n\n

\"digitalYou will be able to see all four colors depending on where the camera is pointing at. <\/p>\n\n\n\n

When you are using this kind of camera with the infrared<\/a> cameras, you will have to make sure that the red sensor is always on and if it isn’t then you can just turn the infrared<\/keyword> camera off. <\/p>\n\n\n\n

After you have made all of these adjustments, you should test the camera so that you know all of the settings are working properly. If the camera works properly then you will be able to take great pictures and that is the most important thing.<\/p>\n\n\n\n

Digital Camera Sensor Information – How To Use Different Colors Of Light<\/keyword> In Your Digital Camera Pictures<\/h2>\n\n\n\n

There are several types of cameras, sensors and image stabilization systems that use red, blue or green screen coloring<\/a> in order to enhance pictures. <\/p>\n\n\n\n

The problem is that by using such light<\/keyword> sources, you limit the quality of the picture because red and green light<\/a> cannot be recorded at the same time and if they are captured at the same time, they will result in artifacts which are much more difficult to remove. On top of that, different colors of light<\/keyword> will also excite the corresponding sensor type differently, thus making it difficult to achieve a clear photo even for a high resolution shot.<\/p>\n\n\n\n

\"Different<\/figure>\n\n\n\n

In general, when dealing with nightscape photos where there is low light<\/keyword>, the camera should be set to use sensor types that can detect low level light<\/keyword> and automatically use white. <\/p>\n\n\n\n

If you are taking landscape photos where there is a lot of shadow, then use black and white modes. <\/p>\n\n\n\n

This will prevent you from accidentally clicking during a very important moment. In addition to that, use a shutter speed that is fast enough to allow for as much contrast as possible between the dark regions and the light<\/keyword> foreground. <\/p>\n\n\n\n

Take pictures with the exposure set to about one sec and try to compose the scene so that the background is slightly brighter than the foreground. <\/p>\n\n\n\n

This will help to make the contrast in the pictures more pronounced and will help you obtain a better picture.<\/p>\n\n\n\n

As a rule of thumb, the colors that make the deepest contrast are generally the colors that make the clearest photo. <\/p>\n\n\n\n

On the other hand, if you are taking a shot of a very bright area, you should use neutral colors such as gray, black or white. <\/p>\n\n\n\n

This will also prevent you from overexposing the photograph and losing detail. Of course, if you are an amateur, it might take some experimenting before you are able to know which colors will make the clearest image.<\/p>\n\n\n\n

Digital Cameras Has Individual Color Sensors<\/h2>\n\n\n\n

Generally all digital cameras have three color sensors, namely: Red, Green and Blue. One thing to note about these sensors is that they are generally sensitive to light<\/keyword>. <\/p>\n\n\n\n

They also tend to turn off when they detect less light<\/keyword> than what is expected, hence the reason why cameras tend to use automatic settings in low-light conditions. <\/p>\n\n\n\n

One interesting factoid about this sensor type is that all digital cameras now-a-days have individual color sensors, which basically means that each camera has a different color sensor. <\/p>\n\n\n\n

In addition to having individual sensors, most of the newer digital SLRs now also have color filters as well.<\/p>\n\n\n\n

\"DigitalIt is pretty much accepted that the color filter on these cameras play a pretty significant role in image quality. The filter controls the amount of infrared<\/keyword> or other kinds of lights that reach the sensor. Generally the more expensive and better quality SLRs do not have color filters and those that do tend to have them in very selective areas such as near the top and bottom of the main aperture blade.<\/p>\n\n\n\n

How Sensitive Are the Colors of the Camera Sensor Elements?<\/h2>\n\n\n\n

What are the camera elements of color? They are usually all red, green and blue, but they can be cyan, magenta, yellow and orange. <\/p>\n\n\n\n

When we see the normal range of colors, all these are close together in the visible spectrum. The red, green and blue are usually combined with infrared<\/keyword>. Infrared<\/keyword> is the third type that the human eye can see and it is usually associated with warmth.<\/p>\n\n\n\n

Now what about the camera sensor elements of red, green and blue. Are these colors sensitive? They are very sensitive to changes in visible and infrared<\/keyword> and their colors may vary depending on the nature of the scene or object. A good example of this is a brick wall with a brick border. <\/p>\n\n\n\n

If the camera sensor element has a red filter, then the red will be over-exposed, while a green or blue filter will cause the color to be slightly under-exposed.<\/p>\n\n\n\n

The camera sensor elements red green and blue are not sensitive to black and white. This is why there is hardly any difference between them, unless you are taking black and white pictures. When you use black and white cameras, they are less sensitive to the changing colors. This is why most digital cameras have the red, green and blue filters. You must really choose your camera model according to the sensor color you want.<\/p>\n\n\n\n

Camera Manufacturers Typically Do Not Specify the Response Times of Their Cameras<\/h2>\n\n\n\n

Camera manufacturers typically don’t specify the response rates of their cameras’ sensors because they know that it is their job to maximize the amount of pixels and consequently the amount of response time so that camera buyers will be happy with their camera and will keep buying their products from them. <\/p>\n\n\n\n

\"Camera<\/figure>\n\n\n\n

The Red 650nm Photon Becomes Corrupted in a Digital Camera<\/h2>\n\n\n\n

The red 650nm photon would register red and blue making a purple color in digital camera<\/a>. This light<\/keyword> feature a small semiconductor that excites red and blue colors at the same frequency which is produced by a device called SPSC which stands for silicon solar cells. <\/p>\n\n\n\n

In fact, the smallest visible light<\/keyword> waves have exactly the same frequency as the SPSC. This would result in red and blue light<\/keyword> coming together at the same time making this color in digital camera impossible to create. <\/p>\n\n\n\n

While there are still theories which claim that light<\/keyword> can be put together at different frequencies this theory has not been proved correct yet. Nevertheless, this was still used in digital camera for many years.<\/p>\n\n\n\n

\"red<\/figure>\n\n\n\n

In the infrared<\/keyword> camera, when exposed to light<\/keyword> comes together and makes a red light<\/keyword>, as it should do in the SPSC. <\/p>\n\n\n\n

When this happens the SPSC would switch to the red light<\/a> mode. <\/p>\n\n\n\n

This way the red light<\/keyword> feature of the camera would continue working and would not become unstable because the red light<\/keyword> photons would register. <\/p>\n\n\n\n

In the long run, people would eventually notice that the pictures taken with this camera would no longer be taken with the red lens. The red lens would register blue or green light<\/keyword> and no longer green and red.<\/p>\n\n\n\n

How would a red 650nm photon get to the blue and green detectors in the SPSC? <\/p>\n\n\n\n

It would pass through one side of the semiconductor layers. <\/p>\n\n\n\n

This would then split the light<\/keyword> into red and blue light<\/keyword>, which would then travel trough the two layers. <\/p>\n\n\n\n

The 650nm photon would then return to the main computer, where it would be interpreted by the microchip. <\/p>\n\n\n\n

This way the red light<\/keyword> feature of the digital camera would remain constant while the other spectrum of the light<\/keyword> gets corrupted.<\/p>\n\n\n\n

CCD Elements Can Pick Up The Invisible Spectrum Plus Infrared<\/keyword> Light<\/keyword><\/h2>\n\n\n\n

A camera lens has been designed to have a focusing system with digital information on the pixels that will be focused by the camera lens. <\/p>\n\n\n\n

These elements are very important as they allow the photographer to focus on an object with more clarity and give better pictures than what they would get with an ordinary point and shoot camera. <\/p>\n\n\n\n

CCD elements can pick up the visible spectrum plus infrared<\/keyword> light<\/keyword>. <\/p>\n\n\n\n

The elements use the color filter system to adjust the brightness of the pixel giving the photographer many more options for photo shots. <\/p>\n\n\n\n

There is actually a three-chip system that determines the color filters and the DIC which are a digital imaging computer.<\/p>\n\n\n\n

Infrared lighting is actually produced by the pixels when a digital photograph is taken and then reflected through the lens onto the sensor. The camera will then calculate how much light<\/keyword> is available depending on what you are trying to capture. The camera also has an internal system that is used to determine what the IR filter should use and how bright the image should be.<\/p>\n\n\n\n

This system is much better than the visible spectrum that the human eye can see and also the infrared<\/a> system which is used in night photography. <\/p>\n\n\n\n

When using a digital camera in the best light<\/keyword> sources to expose the film to are the brightest natural lights such as sunlight, or moon light<\/a>. <\/p>\n\n\n\n

They can also pick up other light<\/keyword> sources that may not be visible to the human eye such as fireflies and other flying insects. <\/p>\n\n\n\n

Digital cameras can also pick up other colors besides the normal red, blue and green.<\/p>\n\n\n\n

Monitor Light<\/keyword> Up and Your Eyes Will See S and L a Little Less<\/h2>\n\n\n\n

The monitor light up and your eyes will see<\/a> S and L a little less than they might otherwise, but not to the same degree as if you used the appropriate brightness settings. <\/p>\n\n\n\n

If you find that your screen is too bright when the monitor lights up, then either you need to make the brightness settings a little higher or that particular model of computer monitor may have an adjustable brightness control feature. <\/p>\n\n\n\n

On the other hand, if the monitor light<\/keyword> up and your eyes don’t see a difference in brightness after adjusting the monitor brightness to the appropriate level, then you probably need to use a different model of monitor.<\/p>\n\n\n\n

You can also keep from over-lightening the screen by using a dimmer switch<\/a>. <\/p>\n\n\n\n

This is similar to turning down the volume on an mp3 player. As an example, you can set the monitor’s brightness to a lower level and then turn it up a few notches. <\/p>\n\n\n\n

Of course, you’ll need to make sure that the monitor has the proper contrast settings so that the display looks good even if the monitor light<\/keyword> up and your eyes don’t see a very large difference in the color of the text or picture on the screen. <\/p>\n\n\n\n

There are some monitor manufacturers that provide a hardware dimmer control. They often come with separate switches for the video and audio sections of the monitor so that you can make the most of these features.<\/p>\n\n\n\n

Light of the Mixture of Red and Blue<\/h2>\n\n\n\n

It has been discovered that when light<\/keyword> is absorbed by phosphors the electrons move from a positive state to a negative one. <\/p>\n\n\n\n

The electrons do not always move in a straight line but rather a random pattern called a photoperimeter<\/a> can measure the percentage of a certain polarity or alignment. <\/p>\n\n\n\n

To change this small alignment into a larger alignment, the electrons must be “flipped” using an electric current so a phosphor is required.<\/p>\n\n\n\n

\"a<\/figure>\n\n\n\n

A phosphor can be made out of many different elements, in fact any element that can produce energy can be used as a phosphor. <\/p>\n\n\n\n

A mixture of red and blue light<\/keyword> can be made by placing a phosphor near a light<\/keyword> source so the electrons will have a positive charge instead of a negative one. <\/p>\n\n\n\n

The current from the light<\/keyword> will pass through the phosphor and will then create a voltage between the positive and negative charges on the phosphor. <\/p>\n\n\n\n

This voltage is then measured and converted into a direct current that can be used to power a device.<\/p>\n\n\n\n

There are many benefits to using a mixture of red and blue light<\/keyword>. <\/p>\n\n\n\n

First it has been discovered that using a combination of these two colors can increase the light<\/keyword> intensity of a light<\/keyword> by about fifty percent. <\/p>\n\n\n\n

This makes the lights more effective at lighting objects than just a pure white light<\/keyword>. <\/p>\n\n\n\n

The ability to use a pure white light<\/keyword> also means that people can light<\/keyword> areas that are difficult to access with traditional lights. <\/p>\n\n\n\n

It is also possible to light<\/keyword> areas that are in motion using a combination of red and blue lights and this could prove to be very useful in the future when it is possible to incorporate video within electronic documents such as computer files.<\/p>\n\n\n\n
