As you can see the specs of the digital camera and was asked to study the details. Before you buy, and be careful. When ready to purchase the digital camera, then it’s a little tip to get in a line as follows.

• The resolution meets the requirements – a 2 megapixel digital camera, the digital camera may not be that many. I’d rather it was a cheap digital camera. And easy to use. If you want to print a large 8×10-inch 3-megapixel digital camera might be more appropriate or a 4-5 megapixel digital camera will provide images that are larger and less mistakes.
• Looking at the battery and charger – This section is the cost of long-term use of the digital camera, the digital camera model uses AA or some application-specific, it would look different, but the battery can. charging for use, it will cost a lot or it may be at least a second time to set the timeout to another set of charges used interchangeably, they do not waste your time.
• The zoom is optical – the digital camera will be able to zoom, optical has at least 2x for imaging the resolution, which by then most digital cameras provide digital zoom past. The results of this digital zoom image quality out to the optical zoom does not.
• The system helps to focus in low light conditions – Some digital cameras will be available in this section in order to make shooting easier, so that this system is very important when shooting in low light or at night.
• Make sure to use an external media – the digital camera model, it has an internal memory to it. Without having to use external data storage media has facilitated greatly. At the same time may not be able to use external data storage media. Which may lead to the shooting that has not taken too much or too limited. So, before the media that there is any external data or not, and so they can be purchased as required.
• Avoid digital cameras that use FDD or compact discs in the bug players – in this section does not bug me but it is recommended that the FDD or CD is priced right and save it, but these media are not able to record the number of pictures. it. And recording at a high resolution coupled with a slower utilization of other media. The advantage is cost. Cheaper than other media.
• Try before you buy – it’s not not not not buy it. Although we do not have much, but if you actually try to touch or handle of a double play, it will contribute to the decision to pick it up. At the same time, it can be used with other models, but the thing is I had the time of the shooting after pressing the shutter to take a long time or not, try the zoom that can be a good one as well. fast or not, finding the focal point of how fast and high contrast LCD screen and use it in various places. How much.
• Look at the software that came with the digital camera - in this section it will be useful in composing or editing to meet demand without having to buy additional software such as Adobe Photoshop Elements and Ulead PhotoImpact.
  If possible, the LCD display screen with a series of high-contrast look beautiful and should have a viewfinder to the viewfinder, saving power of the digital camera.
• The nature of the movie – in this section is not to focus too much or it may be better to have had it around. Because of the motion picture digital camera slides to be quite limited, which is thought to be shooting the video, go to the video digital camera would be better.
• To use the media – media is like a computer’s hard drive that records the image data is stored on. Before being transferred to a computer or other media. The media can be read faster, it saves time to have a lot of work ever.

Digital Camera starts to play a role in our lives so much easier and it will spread to many more devices with which to see and what is the most recognizable. On the phone. Although the resolution is not high, but there is a better approach would have been able to continue to develop even more.
The sense of our  Digital Camera is a sleek, it has been developed to provide higher and in the future may be used instead of film cameras at all. Due to the long term, low cost and ease of use. Moreover, the captured image can be deployed to other parts. Immediately as well. Whether it’s email, the image of the reports, etc.

First of all, we come to know the types of digital cameras, which are two major categories, is a compact camera (Compact) is a camera-ready finished. Easy to adjust or change anything. The functions are easy to use. The ideal is a P / A / S / M or Auto (automatic), Portrait (portrait), Landscape (scenic shots), Sports (shooting sports), Night scene (night shooting). For those who are just beginning to use digital cameras. Another is that digital SLR cameras, this camera is similar to film cameras is the ability to swap lenses. And function in a more compact camera. But there are advantages that can shoot a better contrast. For the sake of a compact camera, it will be cheaper than a digital camera SLR.

The market is not only compact cameras and digital SLR cameras only. But there is another camera that is inserted into the middle of the Camera Compact digital SLR camera, which many people tend to run over a Semi-Pro or SLR-like or semi-professional enough. Most cameras of this type will look like a SLR camera lens, but can not replace it. However, lens quality and features of the better compact camera. The camera will start to get more popular. It is not too high. (May be higher than a compact camera, but not to SLR).

I see before I buy?

Digital cameras will have details or features of each. That these details are the same or somewhat different. We see that the camera has some more details.

Format (type of camera).

The most cameras, it will have two types of Compact and SLR the other, it is the form produced to meet the needs of users using the application of cameras Compact and SLR is SLR. -like, Compact swivel, Ultra Compact and Ultra Compact swivel.

Also known as (name, etc.)

Some cameras have been built and sold in different countries. Will be sold in a country that is not the same as the same camera. The most common brand by Canon and Olympus.

Camera body (the material of the camera).

The material of the camera is an important part to make the camera a sturdy strength. In order to be observed here as well. Most cameras in this section is made of magnesium alloy semi-plastic or plastic composite or semi-metal to provide durability and lightweight. If a metal one, it would weigh too much.

Resolution (image size).

Will tell the camera to another, although not a very important part of it. Due to the size of the image that the camera is in many ways. The size of the camera may not be the same. Which the user may be looking at the camera can not see the need to read the manual or try shooting 2-Self, as the camera has a resolution of 8 mega pixel camera as well. However, the size of the image can be selected from the camera is not the same, some may be at 3264 x 2448, 2592 x 1944, 2048 x 1536, 1600 x 1200, 1280 x 960, 1024 x 768, 640 x 480 pixels, however. Some will choose the 3264 x 2448, 2592 x 1944, 2288 x 1712, 2048 x 1536, 1600 x 1200, 1280 x 960, 1024 x 768, 640 x 480 pixels (the maximum size is the same 3264 x 2448 =. 7990272), which is used to select a desired size, then select the camera that can image a lot, but nothing is wrong.

Effective pixels (the resolution that the real work).

Resolution applications. The resolution of the sensor is able to save the image. Each brand will have a camera Effective pixels (the resolution actually used) is different to any brand that has a lot Effective pixels will be able to shoot the lot size. For the resolution of this is that the performance of the camera. The purchase should be the Effective pixels by a camera with Effective pixels difference is the price difference with the Effective pixels at 3.0 megapixels of the camera will be in the range of less than 10,000. 12,000 baht a camera with Effective pixels at 4.0 megapixels of the camera is in the range of 12,000 to 15,000 camera with 5.0 mega pixels, the price is in the range of 15,000 to 20,000 baht a camera with a resolution level of 6.0. – 8.0 megapixel camera price in the range of 25000-40000 baht Another observation is that it is. The camera has a resolution lower than the 8.0 megapixel camera with flash will be more expensive than the regular price of 3,000 Baht

To select the resolution of the camera, use it to look the usage is. If users want to be photographed in order to send an email to friends or others that are far out to see in 3-megapixel resolution, it can be taken as well. And the price is not too expensive. If you want to compress a 4×6-inch Photo Printer, or print it using a camera with 5 megapixel resolution and better. In 8.0-megapixel camera is used for applications requiring high-resolution applications. Or to use a SLR digital camera, it will be beautiful and have a variety of tasks, the better. The SLR digital camera, the resolution is equal or close to a compact camera is more expensive than it is about 2-3 times.

Sensor photo detectors (the resolution of the sensor).

The ability of the sensor of the camera to get the picture. The resolution is a resolution made at the factory. And most of it will be a resolution that is stuck inside a box 17.2 million pixels (16.6 million pixels – Effective pixels), 3.3 megapixel camera (3.2 megapixels – effective pixels) and so on.

Sensor type (type of sensor).

The sensor is a priority for the camera as much, or it may be said to have a heart at all. Since this sensor is the image and convert it to a digital signal processor to store media. The sensor is said to be the resolution of the camera that can capture images at a resolution of it. For the sensors used are the two types of CCD and CMOS, which is different that the CCD will consume more power than CMOS, but that resolution than CMOS However, CMOS has been developed with a high and more. And more detailed, but still has a few cameras in the Canon.

Sensor size (the size of the sensor).

As the size of the image. This is measured along the diagonal of a 1/3.2 inch (4.54 x 3.42 mm), 1/1.8 inch (7.18 x 5.32 mm), etc. For example, the. 1/1.8 inch sensor size is larger than the 1/3.2 inch.

Sensor manufacturer (sensor application).

Most sensors use the camera where it would be a sensor branded them go because they are supported as well as cameras, Canon is the sensor of the Canon, the camera of Nikon’s sensor of the Nikon etc. But there may be some brands that are used by most other brands of sensors of a camera, it will reflect most of the OEM.

ISO rating (ISO).

Sensitivity is a measure of the performance of another camera. In order not to choose a range of ISO is worth giving away some like 50 to 400 or 100 to 800, but most camera compact, it has the sensitivity to Auto, 50, 100,. 200, 400 and camera SLR, the sensitivity can be adjusted according to needs, such as 100-1600 per 1 / 3 stops, etc. The advantages of the ISO is that it can shoot sharper than high ISO, however. Shooting in the dark, very good high ISO values, it would have been nice to be able to take pictures in low light conditions are good, but the contrast of the image is reduced. But now it has developed a camera system called Noise Reduction up to solve problems in this section. But this system of each camera will be the same as well as technologies evolve.
