Korea Successfully Create Invisible Camera

cahsiji — Sat, 27 Mar 2010 11:47:55 +0000

Human desire to see objects that are not visible to the naked eye. tp seems not a problem today. A clear example, hobbies watching movies can be an opportunity to meet the human desire to peep the life of others.

Therefore, the scientific world on an adventure to complete the demands of human life through the development of peralatanyang be transparent.

South Korea has recently successfully developed a camera that can be transparent through the good parts of the clothes and objects in the fog. Development of millimeter kameragelombang for the second time in the world

camera through pandanus

A South Korean research institute on 19 October last in Yongin city, province Kyeonggi, held a presentation about the capabilities MIRAE, Millimeter-Wave Imaging Radiometer Equipment, or sejeniskamera that can detect millimeter wave so transparent.

In the presentation, MIRAE accurately captured the position and the outline of a car behind a thick screen. Meanwhile, ordinary cameras and an infrared ray camera failed to capture the position and outline of the car.

In addition, the transparent camera capable of taking images of real objects that are in flames and smoke of the fire and managed to detect a gun in the shirt yangdisembunyikan. According to these institutions, they managed to mengembangkankamera transparent after devoting his efforts during the last 3 years. This is the second success in the world.

Secret millimeter wave
Millimeter wave is the main key for the development transparent camera view. The theory of the use of transparent light waves outside the visible light area that can not be seen or felt by humans.

Through the process of millimeter wave image looks relatively long compared with the wave of visible light and infrared rays, we can see objects that are in a state of vague due to the barrier.

Millimeter wave camera can take images of objects, through the acceptance of millimeter wave emitted directly from the object it naturally. This Use camera avoid negative impacts to human health. Does the camera’s infrared rays and X-rays used in already long human life, capable of invisibility?

Rays that can penetrate the barrier
We are able to see through the changes transparent infrared rays emitted from our bodies naturally become visible light, such as infrared rays halnyakamera, although we can not see objects beyond the reach of infrared rays and ultra violet rays.

Infrared light has long waves can penetrate both the fabric and dark clothes to find the object position. The function is now applied to launch a SAR activities.

Additionally, X-ray at the airport is used to detect what is hidden under clothing or in the human body in order to prevent things that are not expected in the protection of passenger safety.

In a recent edition of this, the British science magazine, New Scientist 10produk introduce science can change the pattern of human life on a large scale in the next 30 years. In these products, there are tools we can use to see an object that is hidden, like a Superman.

In other words, the world of science and international technology now make every effort to develop the technology transparent.

University of Utah research team, the United States has developed technology that can track down the movements of people or objects behind a thick wall with a radio transmitter without a cable, the image retrieval method without the cable vertical, or RTI.

United States army also managed to develop LifeReader technology, namely wireless equipment that can monitor heart rate and breathing at the same time a group of people.

Plus, an advanced technology was also developed to transfer the information collected by the miniature digital camera on the glasses worn by blind people to the electrodes implanted in blind people’s tongues. In conclusion, the time soon, the development of science.

SURGERY TRICKS: water dripping

cahsiji — Mon, 22 Mar 2010 05:46:06 +0000

Inspired by the works of FN-ers that contain water, and generally not using the cameras Point & Shoot type, so for me that has these types, the challenge of doing the same thing with all the limitations in the camera (digital) type of P & S is .

My work related to the water I will discuss here, such as Air Trickle, Splash! , Drops of Water and Water Drop

Digital Wedding Photography

Water Trickle, Drops of Water and Water Drop

Requirements:
- Digital Camera P & S (we recommend at least 2 MP resolution, better yet if you have the ability to macro)
- Tripod, Monopods or objects that can be functioned as a camera holder.
- Flashlight or shiny objects such as spoons, used to pre-focus.
- The room with the lighting not too bright (roughly the size of the room as bright as the 4 x 4 with lights PLC 9 s / d 13 W).
- Source of water droplets (faucet, hose, straw or other) with a drop of about 2 or 3 drops per second.

The process of taking pictures:
- Set the water drops about 2 to 3 drops per second. The number of droplets per second depends on the photographer wants, free to experiment.
- Make a macro setting on the camera when there is, and enable the fill-in flash (no auto flash).
- Point the camera at the water dripping, do pre-focus (press the shutter button half). If you can not focus, bring the shiny thing on the water that dripped position to help pre-focus, if still not the focus, help with a flashlight. This is a critical step to obtain optimal results from water that dripped so clear and sharp.
- After the focus obtained through pre-focus, wait until the best water droplets appear, take a picture with the right timing. Should be done many times, so that later can be chosen the best.
- The condition above is not binding, do experiment with different lighting or angle.

S.p.l.a.s.h!
Requirements:
- Digital Camera P & S (we recommend at least 2 MP resolution, better yet if you have the ability to macro)
- A small bottle filled with water

The process of taking pictures:
- Setting the digicam flash fill-in position.
- Hold the camera with his right (or left)
- Hold the bottle of water with your left hand (or right)
- Perform pre-focus (see article above)
- Make a quick movement against bottled water as it spilled on it at once.
- The timing is right, press the shutter button fully.
- Same as before, several times to get the best results.

So little sharing of knowledge, may be useful and safe experimenting.

Here are pictures of water droplets with a variety of forms:

What is Exposure Value (EV)?

cahsiji — Fri, 05 Mar 2010 10:58:13 +0000

Categories: Basic Theory Photography
EV = Exposure Value

EV value is a combination of shutter speed and diaphragm, may also be said as the value of how light / dark photo.

EV number is the number for 1st time exposure (1 take 1 frame), does not apply to double / multiple exposure. More, EV is the result of calculation of speed, diaphragm, and ISO. Following formula:

EV = log 2 (aperture2 x (1/shutter speed) x (ISO sensitivity/100))

In photography, the EV is the amount of light needed for 1-time exposure, the rate of EV also represents the right blend between the diaphragm shutter speed to get a normal exposure, no less and no more. Here is a table with a note EV ISO 100:

So for example, you are in room A is speed 1 / 125 and diaphragm 5.6 and ISO 100. Mean value of EV is 12. And when you’re in the room you get a diaphragm B 4, then to get the EV value (large dark / light) the same, you should use a speed 1 / 250 Since the EV value 1 / 125 & 5.6 with 1 / 250 & 4 are the same.

On the camera feature, the difference we can set the EV suit, changing the EV difference in the camera with changing compensation compensation exposure.Beda one 1 / 2 or 1 / 3. On my camera, Canon PowerShot A70, in P mode, Av, and TV, EV can be set as the above items. When in Manual mode (M), the difference EV can be searched by combining the speed and the diaphragm.

The following are examples of different EV, each with different EV is 1 / 3. I make use M mode on the camera, combining speed and diaphragm for the EV different

No. 1: I took a 0.5-second speed with the diaphragm 2.8 (-1 / 3)
No. 2: I took a speed 0.8 seconds with a diaphragm 2.8 (0)
No. 3: I took a speed 1.0 seconds with a diaphragm 2.8 (+1 / 3)

Note: The picture was not edited, just cropping and resize in PS. Taken with ISO 100. Use of different EV can be adjusted to the needs.

Often we see the camera is writing the specifications (example): SLR Light Meter: EV 1-20 at ISO 100 and f/1.4 This means that if you use f1.4 lens with a diaphragm and an ISO 100 film, the camera makers to ensure the reading value 1 EV of the value of 20 will be accurate.

But if you use f/4.0 lens with a diaphragm, the camera light meter will read a different 3 stops, then the light meter readings will be accurate in the value of EV 4 23.

Note: by using a different lens then the description of a photograph will be different. But when using film with a different ISO, then the description of a photograph will be the same.

Know Your Digital Camera Basic

cahsiji — Wed, 03 Mar 2010 11:35:52 +0000

In this article we will discuss the notion Megapixel and Image Stabilizer. Both these features are familiar to a digital camera products.
Megapixel
The larger a Megapixel camera, then going to get better picture quality. This is the biggest myth in the world of the camera, and it was completely not true. Camera companies and camera stores really clear about this, but they kept on trying to maintain this false perception, not only to maintain even, but they just kept trying to stick it to the customer’s mind. Why?
Because it is this which causes the companies and shops can be a big profit. Simply by increasing the number pixelnya, without other changes more meaningful, they can create a new type of camera, and the customers who were deceived in vying to “upgrade” the camera.
In fact, it is important to REMEMBER, the higher the Megapixelnya, if not accompanied by changes in sensor size, architectural changes or changes in the quality of the camera lens, the image quality of these cameras are even more ugly.
So the function of the large megapixel actually what? The key is the problem of “Zoom”. The greater the resolution of a camera (megapixels), then we can print our photos with a larger size.
But the problem, the needs of the average layman, the only print in 4R size or 10R alone, which can be done very well by the camera with a resolution 4Megapixel. In Figure 1 is a table for the print size.
In addition to the print magnification of problems, resolution can also be useful if we often do CROP on our Photos. if you are not a frequent user is doing a big print or often do cropping, with a 6 megapixel camera is more than enough.
Image Stabilizer
Each brand of camera to use terms different to this one feature. There Image Stabilizer, Vibrate Reduction, Anti Shake, Steady Shot, Optical Image Stabilizer (OIS), Vibrate Compensation, and so forth. That’s all the same function, namely to shake our hands menyetabilkan.
Often occurs in mistaken notion of this one feature. Mistaken more often than tertukarnya understanding between the Shutter Speed and Image Stabilizer. When we photographed the children who are running, if we want our child’s photograph still looked sharp (not blurry), we must menggunakanShutter rapid speed, and had nothing to do with Image Stabilizer. A fast shutter speed allows you to freeze the “object” that we photograph, while the useful Image Stabilizer for shake-menyetabilkan from “Subject” of photographing.
Image Stabilizer So this will be useful when:
- Hand’s hard to not move when taking photos or our hand tremors
- Conducting Shutter Speed shooting with a low (indoors, at night, the effects of light moving waterfall pictures, etc.)
- Doing the photos with a telephoto lens (long distance) eg 200 mm
- Doing the photos macro (close range)
How to work this feature is to place sensors on the lens or the sensor (each different manufacturer). This sensor serves to detect movement or the camera lens. For example padaImage reply Stabilizer lens is placed on, when we move the camera upward, this sensor the lens will move it down, when we move the camera to the left, this sensor will move the lens to the right, and so on so that the image we create will always diusahakn stable and free of turbulence.
Now after knowing the meaning of this Image Stabilizer, we can also learn about the producers of the naughty, which deliberately kesalahkaprahan konsumenakan use this understanding to take advantage.
There are some producers who obviously do not have Image Stabilizer technology, but dare lists similar slogan and even promoting this feature through the brochures and marketing their facilities.
Or there is already have this technology, but due to a camera attached to a low-end cameras will not be possible in terms of price, they ultimately create terms that are similar but it’s really deceptive, such as the Anti Shake DSP, New Anti-Shake AE , etc..
There are also those who simply have this technology and have paired the camera, but because their competitors are trying to fool the consumer, so they went along, too fool consumers with terms such as cooler Double Anti Blur, 4x Image Stabilization, Dual IS, etc..
Image Stabilizer, this false image stabilizer is the only way it works to raise the ISO setting on the camera alone. Shutter Speed automatic so that we get will be faster and because it can also reduce the shock (the object and subject as well).
But for this facility there is a price to pay, the picture quality will be greatly reduced. Because the higher the ISO the image quality will be more noise, lots of freckles are colorful, no sharp and so forth, essentially the picture will look more rough.
In addition there are also other weaknesses, so we can not do photo shoot where we want to use a low speed, such as waterfalls photos so that water could be like cotton. And still there are other deficiencies. But actually, the most ridiculous dariimage stabilizer is false, nearly all cameras can do that, stay raised ISOnya aja. It’s ridiculous.
In terms such as Double Anti Blur, 4x Image Stabilization, Dual IS, and so the intention is that they are real and menggunakanImage stabilizer image stabilizer and tricks. So in terms that their products will be more able to withstand shocks. Fortunately, at least until now I still have not seen anyone use the term Dual Double or who was inside the original Stabilizer adaImage not at all. Maybe in a minute.
So we have to be careful, if you see a feature like this, should first read the manuals or search the internet or know of friends who already know, whether the original image menyetabilkan movement stabilizernya on the lens or the camera, or just raise the ISO only.

Fuji F200EXR, the versatile compact cameras

cahsiji — Mon, 01 Mar 2010 13:06:22 +0000

Finally released as well, a digital camera from Fuji with generation SuperCCD EXR sensor. Named Finepix camera is quick F200EXR similar to its predecessor, but with the F100fd larger screen. This camera is a camera Finepix first in line to adopt the new EXR sensor, and is expected in the coming months EXR sensor will also be attached to a semi-pro camera Finepix S100fs class and super-zoom camera class S8100fd.

For those who do not listen to info about this new sensor, the point is simply that EXR sensor is the result of research that combines Fuji SuperCCD sensor type and type HR SR. Type HR can provide high resolution with low noise, typically used in compact cameras up to a semi-pro camera, while the type SR is jawaranya dynamic-range, is used in DSLR cameras Fuji S series. With the merging of these two sensor technology, you can imagine just by a sensor capability can be obtained high-resolution digital photography is low and has noisenya dynamic range better.
For starters, the following excerpt main features:
• 12 Megapixel SuperCCD EXR sensor (1/1.6 inch)
• F3.3-5.1, 5X optical zoom lens, equivalent to 28 to 140 mm
• Sensor-shift image stabilization
• 3-inch LCD display with 230.000 pixels
• Full manual controls + numerous scene modes
• ISO range of 100 to 12.800
• Super Intelligent Flash
• Face Detection 3.0
• Records movies at 640 x 480 (30 fps) with sound
• 48MB onboard memory + xD / SD / SDHC card slot
• Uses NP-50 lithium-ion battery
On paper it does not appear there is a prominent feature of the row above (except ISOnya can reach ISO 12,800, wow!) Even brand can outperform competitors, especially in Fuji this movie features the average have been using HD resolutions. Even if the record, lens specifications, although very effective fokalnya range (28-140mm), but not the case with maximum exposure. Yes, this Fuji compact cameras like the current generation, preferring to design lenses that are not economically able to open up to f/2.8 as the cameras prior to this generation. But we are not discussing it, we’re like peeling about how EXR sensor is reliable in a variety of shooting conditions.
We started it. Both selected manually or automatically, as EXR sensor can act as three different sensors. When EXR mode set to auto, the camera will determine the EXR sensor to act as anything, depending on shooting conditions. Roles can be selected on EXR sensor is:
• Fine Capture (high resolution), means that the sensor to normal operation with a maximum resolution of 12 MP, suitable for everyday shooting with a normal light conditions (adequate). In other words, is exactly the same fashion as using any digital camera.
• Pixel Fusion (high sensitivity, low noise), which means that by selecting this mode of each pixel that will be combined together to provide a higher sensitivity of 2x, so noise can be suppressed lower. Note that with the combined method of two neighboring pixels is the resolution becomes effective EXR sensor 6 MP.
• Dual Capture (wide dynamic range), the same principle as HDR photography is merging two different photo exposure. But the difference with HDR techniques, we do not need to photograph a few images to be merged on the computer, enough internal systems that do EXR sensor. Principally, half of the number of pixels in EXR sensor will capture images with a higher eskposure (light), while the other half served taking photos with a lower exposure (dark). The two different images are combined exposure by the camera’s internal processor and the end result is a 6 MP image that has a wide dynamic range.
Although this camera can automatically determine which mode is suitable EXR to photograph the situation at the time, but of course the user should determine when kameralah which must use Fine mode Capture, when to use Pixel Fusion and when to use the Dual Capture. Here are some scenarios that allow us to shoot specifically chose EXR sensor mode manually:
• Fine Mode Capture would be used if necessary high-resolution 12 MP, like the full picture with details (landscape) or if the cropping will be done later. This mode is necessary in light of the inadequate and uneven, meaning there is no difference in the area that is too dark or light on one area of the image.
• Pixel Fusion Mode will show his prowess when used in place of less light. If necessary photographed using a high ISO and no flash, such as indoor photos, concert pictures, or where the use of flash is not permitted, just use this mode.
• Dual Capture Mode, a new breakthrough got photos with high dynamic range without having to process through computer software.

Black And White Digital Photography

This mode can be used in the shooting area that has high contrast, there is an area that is very bright and very dark in a field photograph. Without this mode, we will be forced to choose to sacrifice a dark area (shadow) in order to save the light areas (highlights) or vice versa.
We are not so enthusiastic in the first mode, for fine-capture mode is the default mode of all compact cameras that have a high resolution. Besides making the image size so large, high resolution also makes heavy loading process and editing photos on the computer. When using this EXR camera, we feel only two modes need to wear a ‘special’ other fusion of pixel mode (think of it the night mode) and dual capture mode (assuming daytime mode). True if the two modes ‘day and night’ will produce 6 MP resolution images only, but for most people, it has 6 MP very sufficient .use cover, short F200EXR Fuji was able to give a major breakthrough in the world of digital photography has been ‘fixed’ when designing a small sensor that is always a problem with high noise and low dynamic range. In small dimensions, 5x zoom lens camera can play a lot of the normal high-resolution camera, the camera is also capable of high ISO like the Nikon, and capable HDR cameras provide high dynamic range without the need to master HDR in computer engineering.

WORLD photography now really experience a drastic change. The days of filling the roll of plastic mixed with chemicals in the back of a camera seems to be over. Boredom waiting for the film was processed in the lab will end. Era of digital cameras is now menyeliputi anyone, and everyone will try new experiences and take advantage of the progress made in the technology of this camera. Indeed, on the other hand we still see that today’s digital cameras still have a resemblance to the camera as we know. Form of plastic-wrapped box or a lightweight metal frame still attached to the lens that regulates the sharpness of focus and aperture and shutter that regulates how much light can enter into the camera. The only difference is the absence of film as we know.
Experience using digital and conventional cameras do give some sense of an entirely new. At least, the photos taken can be directly seen the results instantly. Results of this immediately is to give another dimension, among others, whoever and wherever a person is able to share photos jepretannya results in an instant. Another thing observation is a process of learning photography became more rapid and can be listened to by anyone interested in without worrying about spending money because they have to buy several rolls of film.
Choice of digital cameras on the market now too diverse kinds. Photography services normally performed by the intermediary of a photo lab, now taken over by there, there on the Internet Web. Digital camera technology that began with the image low-resolution images, it’s far developed than five years ago and still able to maintain the slogan “more beautiful than the original”.
However, on the other hand, had arrived at a degree of confusion when choosing which camera gives the best results, because in addition to technology embodied in today’s digital cameras closer to each other, any price range. Moreover, various camera accessories, such as additional wide-angle lens or telephoto lens, and lighting options using a variety of flash too.
Megapixel
At first glance, competition pixels in a digital camera into an equivalent competition arena as well as computer processor speed competition that every time the PC is always updated within a certain period of increasing gigahertz existing on the market. Therefore, we do not get fooled by the number of megapixels that heralded a seller of digital cameras, because it is true that there are a number of cameras with more megapixels, but not necessarily this camera to be the best.
To remember is that the more sensitive cells are accommodated in the image chip CCD (Charge Coupled Device) which regulates the sensitivity of the lighting, more and more electronic disturbances produced. Only the electronic circuit maker clever and sophisticated that could handle this problem. And nowadays, it becomes a serious problem, because the producers who have not seen the best CCD chips today are indeed observed will be dominated by companies like Canon, Nikon, Fuji, Sony, and others.
