Inside Story Of Digital Camera
The quality of a digital camera is now a luxury but essential component of daily life. Digital cameras are available in a day. Several hundred dollars on a camera is available now. The camera is available in various brands and add with the new feature and function. The digital camera users are increasing every day....
Check how the camera works conventional camera and light on the mechanical and chemical process through the lens of the film in the top of the Shutter. Chemical step in the process of printing the images from this film. Digital cameras are electronic and processed in the light of the CCD (Charge-Coupled Device) sensor on. Full digital photos through the process of electronic copy, then print. CCD / CMOS - This digital data (images) can be used in all types of digital devices.
Compact vs SLR Digital cameras can be broadly divided into two. Shoot and Point (Compact) and SLR (Single Lens Reflex). The camera itself is compact cameras, most functions are automatic, which has its own program in the light settings. The setting of all functions, users can manually SLR, but otherwise the user must have good knowledge about cameras and photography should be. SLR cameras, the size, weight and cost more than the compact cameras, lenses and flash and also have the option to use. One of them is a SLR camera for professional photography. This compact digital camera for general users, so there's talk now.
Important digital camera features / functions.
1. CCD (Charge-Coupled Device): CCD digital camera has a silicon chip where the image is recorded. CCD or CMOS sensor digital camera is the most important and expensive devices. It consists of millions of pixels. When the light through the lens of the active layer of the photo sensor hit an electric charge generated in the pixels in the layer below. Depending on the amount of light is different for different pixels electric charge. Million pixels to create the electrical charge it is a combination of a digital image.
How many mega pixels resolutions digital camera with the ability and means of the camera sensor. The more stars the more mega pixels, you can print out to restore the image quality. Many of these mega pixel camera of the present status symbol. Photo is postcard size 6 "x4". I do not need to print larger than the exceptional. 7 "x5" photo print quality is not enough for a 3 Mega pixel cameras!
2.Lens: Second most important device in the lens of digital cameras. Nikon, Canon, Olympus lens companies have prepared themselves, and Sony, Casio; Panasonic companies are using third party lenses.
3. Zoom: Zoom lens, an important feature of the camera. 'Zoom in' to the lens means that distant objects appear to have dragged, and 'zoom out' means to push away from the nearest object to the lens to appear. Two types of zoom: optical zoom and digital zoom. Optical zoom uses the lens of the camera. This is the lens through which the object will be larger than the image quality will remain the same. Fit zoom lens with digital objects, or no. Here is a portion of the displayed image is a digital process, and the image quality decreases. For example, the more graphic images zoom in on the program, the image becomes more blurred.
So careful, the egg will not zoom digital camera, optical zoom power to do much. Zoom will be greater than the distance of the image. Optical zoom is the ability to express a lot of time with focal length. For example: 5.8-17.4mm, 35-105mm, etc. The number of the optical zoom power at the end of the first number is out. 105/35 = 3. The 3X Optical Zoom. The distance from the sensor to the lens focal length sense of the words.
4. Focusing Range: the lens of how distant and nearby objects to take pictures of how they are expressed with Focusing Range. Most cameras Infinity (infinity) distance to the object can be added, so how close objects (Macro) could be the same. For example: 1.6 ft (0.5 m) to infinity (wide), 3.28 ft (1.0 m) to infinity (telephoto), 8 in. (0.2 m) (close-up), etc..
5. Aperture: the lens Aperture Iris Diaphragm to get to the open use of the word. To control the light entering the lens through the round holes of the Aperture Iris Diaphragm or small / large. The increased amount of light entered the lens is reduced. f / # is a number indicating the size aperture. Will be smaller as the number of the light gate.
6. Shutter Speed: The center of the lens and the light sensor to prevent the shutter cover. He stuck it to work. It is open to the light entering through the lens of the sensor. Shutter release button is pressed; the photographs with the look of the shutters closed and open again. Shutter speed of light between the lens and prevent sensor cover (shutter) to open and close to the time gap. This means that the cover is opened, it should be controlled. This is usually less than one second, in some cases may be higher. Speed shutter 1/90, 1/125, 1/250, 1/500, 1/1000, 1/1500 seconds is expressed as. Aperture and Shutter Speed for a night and day are different types.
7. Exposure Control: Aperture and Shutter Speed and precision can be adjusted to take beautiful photos. If you do not adjust the shutter speed and aperture the image "over exposure" (more light) or "under exposure" (in black) will be lost. Aperture and Shutter Speed are manually controlled by the professional photographer take the picture. Automatic compact camera automatically controls are mode. However, it may not always be completely accurate.
Pr-programmed Exposure Mode setting is present in most camera is, there is still work to be selected. Such as: Landscape, Portrait, Sunset, Beach / Snow, Back light, Macro, Night Scene, Fireworks, Panorama, Sports, etc.. The more there will be more of a mood.
8. ISO (Sensitivity): This is a size, the CCD or CMOS sensor which is sensitive to the light touch, how much will react bundle. Low ISO Rating - This means it is less sensitive to the actual exposure will be needed for more light. High ISO Rating - This afternoon will be just the opposite. Generally, ISO 100 - ISO 400 is used more. ISO Rating higher than the speed of light the camera will take better photos more.
9. Image Stabilization: A very useful feature. If the image is blurred vibrate the camera exposure time. To reduce this problem of image stabilization or vibration reduction systems. If the exposure time the camera vibrate the sensor itself is little change in the balance. Again, like Fit zoom Optical Stabilization important, not digital.
10. Viewfinder / LCD Display: Viewfinder / LCD Display: The image of the wholeness of the person through which we view it in Finder. We would like to withdraw the scene photos showing how it frames the view of the Finder or the LCD display to satisfy the shutter button is pressed, then shots. The photographs on display to see whether I have been a good film, if you can delete. View Finder instead of the display of the sun light exposure. Both the Finder and display the view. Batteries can be quickly done using the display. Display at least 3 inches (Diagonal Repeat length) should be.
11. Auto focus: zoom in or zoom out the image forming lens, or when we have to manually move the camera in view of the Finder / display the image to see a position the focus point. This action will move the lens back and forth manually set the camera's auto focus enough.
12. White Balance: Images from the unreal to the real agree to eliminate the effect of the color white as the white balance process. In particular, where the white majority in that case, if the light switch is florescent a bluish tint to the white color image to gray, which makes the unreal.
13. Flash: The compact digital camera built-in flash 3-5 meters cover the distance. On, Off, Auto Flash, as well as light and the mood of the user manual to see what the camera can be used properly. Infrared sensor with some cameras, which detect the Flash Adjust the camera and the image, becomes the target distance. External Flash Unit is the use of cameras, SLR cameras, but in most cases.
14. Red Eye Reduction: human or animal - animal eyes, the retina can be seen in the picture sometimes has a red color. Flash light is a small angle shot of the back of the lens. Retina of the eye, such as need. Flash light and compact cameras are very close to the lens position. portrait or close-up shot during the flush of light when light is reflected directly from the lens and the retina is the retinal image in red. To avoid this problem for the Red-Eye Reduction Flash Mode.
15. Continuous Shot Function: a faster moving object (car) or person (player) or Continuous Shooting photographs for Burst Mode. The shutter button is pressed the mode a number of consecutive camera images (series) and take a shot with the will to save memory. I want the best from the rest of the film, you can delete. The series of images of the camera and the recording speed is faster.
16. Video with sound: the sound and video features. It is not equivalent to having a video camera, video clip, just a few minutes. Who needs a feature to record a special moment?
17. File Format: File Format supports all three types of cameras: JFEG, TIFF and RAW. JFEG (default format) Compression Format is the file size smaller and less important information is necessary to subtract the image. TIFF format and the compressed image data are not removed. File size is larger. Format is a compressed RAW, the image of the whole digital negative.
18. Storage Media: Digital camera with the memory (12 MB - 32 MB) is that it is very small. In most cases, to buy the memory separately. So before buying a camera should be to buy a memory card. How should the cost and readily available. The memory card, CompactFlash, Secure Digital, SDHC, xD Picture, Memory Stick, Micro Drive, and SmartMedia. The SD card and SDHC card is the most commonly used and readily available. Normally 2GB - 4GB of memory is enough. All pen drive or CD can be copied to the memory is empty. The 4GB memory 10 MP camera and 8 MP camera JFEG format about 1150 to 1450 in the image can be saved.
19. Power Sources: Digital camera with LCD multi-function and the need display electricity enough. So there is no alternative re-chargeable batteries. Generally, three types of batteries are options. A) Lithium Ion battery, it would have the camera and the camera is charged with. Exactly like the mobile phone. New battery first 8-12 hours of full charge is charged (see manual). The camera batteries are a variety of sizes and models. After several days of using batteries are not charged long time. Those who regularly use the camera if possible, a reserve battery that I bought it. B) Lithium Ion battery charger, all the same, only difference is a separate charger, the charger charges the battery from the camera. The advantage is, buy an extra battery with the camera on a stand-by charge of the work of another. C) Rechargeable AA NiMh (pencil batteries). In most cases, batteries and charger option is to buy it separately. MAh capacity batteries of different types of charges may be
20. Interfaces: USB cable with all the cameras. The only connection I have with the camera so the camera can be added directly to the TV.
21. Self-timer option: any group with a particular scene or your photos to this option. Tripod or camera view of the above stable anything you choose this option, there wait 5-10 seconds after the shot, take the camera itself.
22. Photo Editing Software: A Free Photo Editing Software is with all camera. I get what what simple flowers. This program is installed on the computer and photo editing work.
23. In-Camera Photo Editing: In-Camera Photo Editing tools recently latest camera models are. The basic image editing tools with the camera to be on display. For example, the light / contrast reduction - increased, the size of a small, unnecessary parts are removed, close-up, etc..
Check up to buy a camera purchase Does not match one's preference and priority to another person. The features / functions that you can now make yourself in any kind of camera you need, he must have features like cameras, and what if any features good, but it is not so. Those who have been using a digital camera can take advice from them. Take the first decision: What will mega pixels, optical zoom is, the display size and your budget. The favorite feature / function to have a list. I do not like the name of the only brands, recently Leading companies in the camera all the good values. I can not find your desired camera view and the following Sites:
- http://www.whatdigitalcamera.com
- http://www.dpreview.com
- DigiCam Resource Page
- Imaging Resource
- Digital Camera Info
- PriceRunner
The company website can see the camera manufacturer. I find that there is no certainty that 100% of your mind, otherwise you may need to be some compromise. If you choose a camera, the brand and model of your full name and Features of note. I can see the various reviews on the site about your favorite camera experts say are the key. Now go to the camera shop to see everything better (price, service, guarantee, package and Acer), like when you bought. Congratulations! The cost of the shop is not much of a difference. Save a few dollars to buy from the store where the camera will not be a problem if they give you good service!
After purchasing the camera what to do first However, we think that it is tough curiciti ! Do not know, or quickly open the Options button, or movements of the right not to know .. Fresh new camera is now helpless guinea pig, laboratory-like conditions! First of all check that with the camera. After 30 minutes of patient packet User Guide / manual of instructions. PDF format on CD recently read a computer manual, which will be given. According to the initial instructions were added to the end of the rex familiar with your camera. There is no menu and no option to do a button, etc. Once you know your darling will get out shot by the most experiment started. Welcome to the world of digital cameras!
The most commonly used options on compact cameras automode image.
1) Select the camera on Auto Mode. Ii) the most important scene object / person viewfinder / monitor through the focus area (center point) to compose. 3) Shutter bottom half (50% of height) to keep constant pressure on the area. Now you will view the camera image settings for the program. When you compose a frame color has been changed or there is a beep, it means the camera ready. 4) Now press the shutter button half of the rest. The film will put the camera to save memory. Just this moment, the camera may be a beep. 5) view / play options screen, select the image you can see. Note that for the time and location of the image directly to the pre - the manifest options to select a mood to do if he is the kind of mood. The camera is easy to compose.

Last word Technology is not to say their last words. Face Detection, Blink detection, Smart Auto scene selection, and the new features coming in the market for new camera models, you will. However, the last being a good image, the image is not just for the camera, it requires a skilled man behind the camera. A human expert to try and practice. The Perfect Digital Camera. Experiments of this, but if you do not delete the image, there is no additional cost. Your camera which features / functions that use them properly.
