Having a good understanding of some of the operating mode of the digital camera so helps us to effectively control the exposure. This article will attempt to explain some common modes of operation are you good DSLR camera, pocket camera is a sophisticated and super-zoom; aperture priority, shutter speed priority, program mode and manual mode.
What is Operation Mode Camera?
Mode on digital cameras allows us to control the exposure parameters, in particular shutter speed, aperture and ISO which is the basic parameters of photography. Several modes automatically determine these quantities, yet another mode to manually control it allows us to taste kita.Dahulu mode when there is no camera, the photographer must decide for themselves all the parameters of shutter speed, aperture, and select the type of film to be used. To calculate the intensity and amount of light, they must use a metering device (see the workings of the camera metering) and a separate measure light choose exposure information, which is then used for the camera settings.
Since the introduction of SLR cameras capable of measuring light coming through the lens, metering equipment becoming obsolete. Since then, the automatic mode is also introduced by the camera manufacturer, where the camera will measure the light coming through the lens and also calculate the right exposure. Mode that currently exist (almost all digital cameras grade semi pro to pro) attempted to bridge between semi-automatic and full operation manual-style photographers of the past.
Types of Camera Mode
There are four main types of camera modes:
Shutter Priority (Tv or S)
Aperture Priority (Av or A)
1. Program Mode
In program mode, the camera automatically determines the Aperture and Shutter Speed for us based on the amount of light coming through the lens. If you find a defining moment and do not want to think anything direct snap, use this mode.
The camera will try to balance between the shutter and aperture, if we turn the lens into a bright area, the number is automatically enlarged aperture while the shutter speed is maintained at a fairly rapid rate. Point the camera into the dark area and the number will be smaller aperture to retain the shutter getting too blur.
There are ways to change the automatic measurement of the camera, by turning the control dial on the camera. If we turn the dial to the left of the camera will be “forced” to slow down the shutter speed and aperture adds. If rotate dial to the right, the camera will be “forced” to speed up the shutter speed and aperture decrease.
2. Shutter-Priority Mode
In priortiy shutter mode, we manually set the shutter speed and the camera value automatically selects the aperture value to our amount of light entering through the lens. This mode can be used when we want to freeze motion or if we deliberately wanted to create a picture blur. If there is too much light, then the number will be larger aperture (smaller aperture) so that the amount of light entering the lens will be reduced. If too little light from entering the lens aperture numbers will shrink meal (bigger aperture) so that the more incoming light lens.
So in shutter priority mode, shutter speed value will not change as a constant (as our setting), while the aperture value will vary depending on the amount of light.
3. Aperture-Priority Mode
In aperture priority mode, you set the aperture size manually and the camera will determine the shutter speed according to the amount of light entering the lens. By using aperture priority mode, you have full control over depth of field (depth of field), because we can decrease or increase the aperture and let the camera calculate the shutter speed
Using aperture priority mode is a safer way to operate the camera because of the risk of being under-exposed photo (dark) or over-exposed (too bright) quite small. Why? because the value of the camera shutter its fairly wide range, from 30 seconds to 1/4000 second (or 1/8000 sec advanced on camera), which is sufficient for a variety of light conditions.
4. Manual Mode
As the name suggests, we control the aperture value and shutter speed the camera completely manually. You must select the aperture as well as shutter speed values. This mode can be used when shooting objects photo lighting conditions it makes the camera “confused”. An example is when we take friends on a very bright, the camera will probably misjudged the exposure so that the face of a friend so that black sand shore is not over-exposed. In cases like this, we can change the mode to manual and perform metering by measuring exposure in the face of friends and then determine the aperture and shutter speed manually based on metering earlier.
Manual mode is also useful when for example we take a panoramic, so happens consistency. Generated panoramic images stitched from several photos, and aperture value and shutter speed should always be consistent so that the final results will be consistent no panoramic photo mottled dark and there was light.
How to Change Camera Mode?
Modifier keys camera mode usually looks quite striking,, a play button that written: P – S – A – M (Nikon DSLR) or: P – Tv – Av – M (Canon DSLR), are some examples:
In some professional grade cameras, the mode dial is not shown prominently, on the Nikon D300S, for example, there is only a small button to the right of the inscribed MODE.
How is the ISO?
In most DSLR cameras, the ISO does not automatically change if we replace the above modes, so we have to specify the ISO manually. If you do not want to use the ISO settings manually, use the “Auto ISO” on camera, and then set the maximum ISO in “800-1600”, if you feel too much noise, change the maximum ISO in smaller numbers.
How With Other Camera Mode?
Some camera entry-level and semi-pro also has another mode, such as “portrait”, “landscape”, “macro”, “sport”, etc., depending on the type of camera.
