Basic of Camera

In this article we will discuss about the basic of camera. Did you know how camera can capture the image? In this article we will talk about this matter. But notice that all of content in this article are just my opinion. I just talk about my little understanding about camera. So if there are something wrong please make correction. You can write comment to make all clear.

Okay, lets talk about the part of camera. Look at the picture below

Basic Diagram of Camera

Here are the brief explanation. Objects can emit light with a specific pattern corresponding to that object. That light will be captured by the lens and enter into the camera. That light will pass through a small hole called the aperture. Next, the light will pass through Sutter. Sutter can be described as a window that can open and close. Next, the light will touch the sensor surface. The pattern on this light will be recorded by the sensor. Next, sensor will convert the pattern into an electrical information. Next, the level of information will be strengthened by an amplifier (ISO). Next, the information will be processed by the image processor and compress it into a jpg file. Finnaly, the file will be stored in the memory.

Many of pocket camera and SLR camera support full automatic mode, semi automatic mode and full manual mode.

Full automatic mode, all of camera element setting already done by camera. The main purpose of this mode is to produce clear and sharp image. So this mode is often use flash to ensure the object can be captured clearly.

Semi automatic mode, we can decide some setting like exposure, ISO, sutter, aperture, and flash but we can not decide all elements at the same time. There is two mode of semi automatic mode, they are sutter priority and aperture priority. So when we decide the sutter speed value, the camera will decide the aperture value. But when we decide aperture value, the camera will decide the sutter speed value. At this mode we can still easy to control the exposure level. The camera will attempt to reach the exposure targets that we have set before.

Full manual mode, we can decide all of camera elements setting at the same time. But we can not control and set the exposure level. Camera will not attempt to reach exposure target because there is no exposure target at this mode. The result of exposure level is depend from combination light, ISO, sutter and aperture which are we set before. This mode can be use to produce non standard image and suitable for advanced photographer.

Another basic of camera elements which should be notice are:
1. ISO
2. Sutter speed
3. Aperture
4. Flash
5. Exposure
All elements above will be discussed at another article at this blog.
