Before using a digital camera we must know the type and function of components of the camera. Types of digital cameras that we discussed was the Pocket Camera (Point and Shoot Camera) and Digital Cameras SLR (Single Lens Reflex).
Type Type Digital Cameras
Pocket Cameras (Point and Shoot Camera)
1. Optical zoom
That image enlargement facilities conducted by a combination of repositioning the lens.
2. Digital zoom
That is the image magnification failitas done digitally. This process is actually just a process of enlargement crooping and using the camera's internal software. Zoom has resulted in blurred images (blur).
3. Resolution up to 3.1 mega pixels.
Media scene can be a conventional lens. LCD, or a combination of both
Semi Professional Digital Cameras
The camera has a lot of this type designation, among other prosumer digital cameras and advanced camera. Giving the name associated with function and a unique target market. This camera is designed for those who want troubled by setting the diaphragm and the other talismans of photographic techniques.
With this camera they can set the distance manually and zooming mode or even the macro facility is very helpful in obtaining quality images and the desired effect. In general, the advantages of digital cameras of this class is the standard lens used, namely 35 mm lens.
These lenses are similar to a standard lens on an analog SLR camera, but with special designs tailored to the characteristics of digital cameras. Other technical advantages of manual and automatic control at the focus, aperture, speed and lens opening. Resolution camera of this class is between 3.1 megapixel to 5.1 megapixels. The offers complete facilities make this camera very attractive, as well as being the most popular among all classes of digital cameras.
Digital Camera SLR (Single Lens Reflex)
This SLR-type digital cameras, as well as analog SLR camera, also uses a lens that can be removed and replaced with a lens diameter larger or smaller as needed. In addition, the placement of buttons and basic functions of these two digital cameras are not much different. The basic components of this camera can be seen in the picture. There are 2 things to consider in using a digital SLR camera, the lens and flash.
Digital Camera Components
The lens is the first filter media when we scan an image to be stored. Therefore a basic knowledge of digital camera lens is very necessary. The camera lens is didiesain use computers to improve accuracy. To increase the sharpness of the lens, the lens is coated with certain chemicals. Here are some types of lenses used on digital SLR cameras:
1. Standard Lens
Standard lens is a lens that becomes a standard component of the camera. The size is 50 mm. The character of this lens is to provide natural shots. These lenses are suitable for medium-range shooting.
2. Wide Angle Lens
Wide angle lens is a lens that is used to capture large objects in the viewfinder field is limited. The character of this lens is to make objects smaller than actual size. The size of this lens is varied, including: 17 mm, 24 mm, 28 mm and 35 mm.
Besides, there are also wide-angle lens with a diameter of 14 mm, 15 mm and 16 mm. The lens is called a fish eye lens lens.
3. Tele Lens
Telephoto lens is the opposite of wide angle lens. Telephoto lens to zoom function, but the narrow viewing angle. Which includes a telephoto lens is a lens with a size of 70 mm and above. Another function of telephoto lenses is to make croping and focus on a particular object and blur the objects in the vicinity.
4. Zoom Lens
A zoom lens is a combination of the three types above. that is the standard lens, wide angle lens, and telephoto lenses. The size of the lens is not a fixed size, but rather a certain range of the lens, eg 80-200 mm. This type of lens is the lens of the most widely used because it has a character that is flexible and wide range of lenses is enough. Thus, if you want to use a certain size lens users stay rotate the lens size as needed.
5. Macro Lens
Macro lenses are usually used to target small objects. In this digital camera, macro-scale enlargement done digitally and not be done optically.
All types of lenses have the same characteristics, namely the smaller the size of the lens, the more wide-angle that can be reached by the camera.
Tools sights
All types of lenses have the same characteristics, namely the smaller the size of the lens, the more wide-angle that can be reached by the camera.
Tools sights
Camera sights
The device camera sight is a small window to see the composition of the image that is photographed to look at the composition of the image that is portrayed. One thing that is important in the sight of this, namely accuracy. Each type of device has advantages and disadvantages sights. In digital cameras, there are three types of devices sights are:
1. Parallel Optical sights
Parallel optical sight is the same sights that are owned by the analogue compact cameras. The lens is placed parallel with the image scanner lens. This lens has a level of accuracy is not interconnected. Parallel optical sights can be seen in the picture.
2. Sights LCD (Liquid Crystal Display)
This LCD sight of the small screen on the back of digital cameras. These sights have a level of accuracy better than optical sights because the image that appears is reflected from the camera lens. The weakness of sight LCD is the delay time (delay). Time delay is often annoying when taking pictures separately for proper documentation that require moment when shooting. LCD sights can be seen in the picture.
3. Optical sights TTI
TTI optical sights (Through Dither lens) is a sight that has the highest level of accuracy because the sight of this type take pictures directly from the camera lens using a prism reflector objects. This type sights only owned by the SLR camera. TTL optical sights can be seen in Figure

Steps Taken
Basically all digital cameras will do the composition of the process, color and focus automatically. Auto focus mode will help you concentrate on an object, not on camera. Step-by-step photography using digital cameras:
Quote: Enable Camera
Activate the camera and set in automatic mode. To conserve battery power, turn off the LCD and use pernbidik sight optics available. Quote: Desired Object Snap
Sight lens or lcd will display the object you are going to portraits. Use the zoom button to obtain the right composition. If a sight to bias or out of focus, you can check if your digital camera to provide a reducing bias. Quote: Auto Focus
Place objects that would be. If the picture is not sharp objects, use the auto focus mode. Scale image sharpness depends on the type of camera you use. For the auto focus to do when you hit half the sights. Quote: Automatic Aperture
In photography there are so-called aperture lens, the lens wide open sights that would be to scan images. Aperture automatically on a digital camera is detected based on the amount of light received by the sensor. After that optimal lens aperture can be determined by pressing the button half sights. 1. Normal position the shutter button 2. The position of half-press the shutter button Quote: Auto Blitz
If the incoming light is less, automatic aperture (autoexposure) will activate the flash automatically. In the active state is seen that the indicator light will blink when you press the button half sights. Quote: Auto white balance
White balance is a method of screening at the time of the conversion process from white to black gradation gradations of color. The method automatically adjusts the color proportions for white colors still appear white in photographs.
Quote: Image Resolution
The digital camera has a standard resolution that can be used, among others.
• 256 x 256 pixels resolution is often found in early editions of the digital camera. But the picture quality does not meet the standards of print. Total pixels at this resolution is 65,000 pixels.
• 640 x480 pixels - the resolution is the lowest resolution to print a standard camera. Resolution imbiasa used to look good web standards used on the homepage or to keep in touch via email. Total on this resolution is 307,000 pixels.
• 1216 x 912 pixels - this resolution is the lowest standard of megapixel resolution. This resolution is good enough to be printed in standard format. Total pixels at this resolution is 1.109 million pixels.
• 1600 x 1200 pixels - this resolution has a number piksei nearly 2 million pixels. With that resolution you can print with a size 10R. Resolution digital camera at the moment already exceeds 10 million pixels.
Standard resolution appropriate for a particular print size, "Kodak" issued a recommendation table minimum resolution for standard photo prints, as in the table below.
