Learning digital camera technology in Introduction


safety has developed, as well as the world has developed into an era of digital photography. people with easy-snap take photos. Manufacturer vying always release the latest products, ranging from pocket cameras, prosumer until DSLR. language ad that states will produce quality images popping up just so that consumers are interested in buying a digital camera is advertised.

So many people who believe that more expensive camera's better outcome, the higher the pixel the better the picture, and even then not completely wrong or right.

It is true the more expensive a camera usually gets a lot of features and functions that are getting on camera, but without adequate knowledge about the features and functions are typically users only use the automatic features (AUTO) to take pictures, why continue to buy expensive if just using AUTO affection not if the other features that are not used.

So is the number of pixels usually also be a material consideration in buying a camera, it is true also that the higher the resulting image is also sharper, but if the picture is just to print postcard size or even just to be fitted mediated social networking sites like facebook and others anyway enough with a small number of pixels.

Apart from all that is written above, we are so disadvantaged by the digital cameras available today, especially for connoisseurs of photography as well as ordinary people who want to learn photography, because the results can be directly viewed, ugly or less satisfactory results stay clear and snap again.

Before we learn about digital photography is useful to know in advance the features / functions / modes that exist in digital cameras, almost all types of digital cameras are now equipped with a mode, and the mode itself is divided into AUTO mode, SEMI FULLY AUTO mode and MANUAL mode.



Below are described the functions of the existing modes:

AUTOMATIC MODES

AUTO MODE:


I think about the auto mode need not be described in detail because almost all digital camera users to use this mode to take pictures.



With this mode when the camera is directed to the object which we will take, the camera will automatically select the shutter speed (the speed of opening and closing the shutter), aperture (diagfragma / small large shutter aperture), ISO (image sensor sensitivity to light), white balance, focus , and the flash is something to take pictures dimaksud.Biasanya with this mode will produce a good picture in any situation.

But keep in mind the auto mode sometimes the camera can not automatically generate an image like what we want, then of that plus some fashion / function that is in auto mode.

Portrait MODE:

When going to take pictures of objects in close-up, move the setting on your digital camera on automatic mode.Secara portrait in portrait mode, the camera will select a large aperture (large aperture shutter), which means that the main object of the picture we will focus while the background becomes out of focus / blur.


To produce good pictures using the portrait mode, we must be close to the object which we will take the good with the way the zoom or closer to the object, for example if we are going to take a close-up someone, just take a picture of the face to the extent of the shoulder, then the result will face will be the focus and the background out of focus / blur.


MACRO MODE:

Almost the same as the portrait mode, but the macro mode is more suitable for taking pictures of small size objects such as flowers, insects or small objects lainnya.Setiap digital cameras have different capabilities including macro focus distance differences as well (the average distance of the focus for point and shoot camera is 2-10cm).

To take a picture macros needed stability in holding the camera as if it moved slightly from the focal distance of the resulting image will be out of focus.Maka usually necessary for decision aid macro tripod, and in addition a built in flash is not recommended, because the result image will be over exposure / too bright.

LANDSCAPE MODE:


When in portrait mode and macro mode the camera will select a large aperture, then in landscape mode the camera will select a small aperture, which means the picture we take will focus from the front (foreground) to the back (background) or in other words all the images that will capture tips look sharp.

It is suitable for shooting wide landscapes.

SPORTS MODE:

Sports mode / action mode is designed to take pictures of moving objects, such as man's running, car racing or any other moving objects.

The purpose of the sports mode is create an image of a moving object with a sharp caught (freeze the action), we can try to take pictures of people who are jumping.

NIGHT MODE:

Night mode is enabled for image capture at low lighting situations, usually at night, and the necessary camera stability when using the night mode because if there is little movement of the resulting image will blur.


FULLY MANUAL MODE

MANUAL MODE (M)

By using the manual mode we freely control the settings according to our will but keep in mind that we need to think of using a shutter speed, aperture, ISO, WB, flash and others to produce images of sufficient lighting, not too dark and not too bright . To use the manual mode is needed exercise and habits in controlling the camera.

Congratulations to experiment with your digital camera, determine which are the most frequent mode or suitable for you, and feel free to always try and experiment with the modes on the camera anda.Saran, criticisms and questions about this paper is expected that this paper more useful.

SEMI AUTOMATIC MODE

When in auto mode, the camera will think for themselves and determine the setting by itself according to surrounding light conditions by setting the semi-auto / semi-manual, we will determine the setting and the rest of the camera will adjust our settings with light conditions exist.

The following are the modes that exist in the semi-automatic mode:

PRIRORITY APERTURE MODE (A or AV)

In this mode we will choose the size of diagfragma aperture / shutter in the lens and the camera will adjust the ISO setting and shutter speed itself. diaphragm / shutter on the camera display is the F / number, eg f/4.0, f/4.5, F/5.0 etc. until F/32.

The smaller the number on the F / number means the greater the aperture on the lens diaphragm (if we choose F / small number means that we will get a small focus area as well, an example for close up or macro, because we only want to focus on just the face and background a blur)

The greater the number on the F / number means that the smaller the lens opening in the diaphragm (with a small diaphragm means we will produce a focused image from front to rear, examples of landscape photos)

SHUTTER PRIORITY MODE (S or TV)

Shutter priority to aperture priority almost the same, except that here we choose the speed / close shutter speed and the camera will adjust the aperture setting, ISO automatically. Shutter priority on the camera display will be shown with the numbers representing the speed that we choose, for example 1 / 400 ", 1 / 250", 1 / 100 ", 1 / 60", 1 / 30 "and so on up to 30".

If we would take pictures of moving objects and want to make the object a "freeze" or silent then we use a high speed (fast shutter speed).

Slow shutter speed is usually used in cases where the light around us less (dark), slow shutter speed can also be used to create a blur effect on a moving object, for example if we take the waterfall using the slow shutter speed (between 1 / 5 "to 1 / 15 ") then the water will seem as white as cotton.

Note:

if we use a low speed, then the necessary stability in holding the camera or use a tripod to prevent camera does not move, because the slightest movement at low speed will produce images that are out of focus.

PROGRAM MODE (P)

Usually called the "Program AE" (program auto exposure / auto lighting program). function is similar to fully automatic, but here we can set the white balance, flash, ISO, etc. manually.

FIELD OF AUTO-DEPHT (A-DEP)

By using this mode image objects from front to rear will focus on its own, with a half-press the shutter we can control the focus as we want.
