Using the Exposure Mode On Camera DSLR and mirrorless

Using the Exposure Mode On Camera DSLR and mirrorless

Photography. In any digital camera, either digital SLR cameras, mirrorless camera or pocket camera (rather sophisticated), always provided the wheel on top of the camera where we can choose the mode of camera operation: And they always have at least a choice like this: Auto, P, S (Tv), A (Av), M and Scene. You can see the wheels camera mode in the example of this photo:

 

 

 

Note that Nikon and Sony use the notation S and A, while Canon and Pentax use the Tv and Av, they are the same but just different notation.

 

This code stands for: Auto for auto, P for Program Mode S or Tv for Mode Shutter Priority, A or Av for Mode Aperture Priority, M for Manual Mode and Scene mode for automatically customized with the option type of the object to be photographed.

 

Let's peel code and mode selection on the camera in order to more clearly:

 

Auto mode

Auto mode is usually marked with a green camera icon, with letter A. In this mode, the camera will attempt to analyze the object of our image and determines all the camera settings. If there is a term point and shoot (viewfinder and snap) without having to change anything complicated, this is what the auto mode.

 

It looks nice is not it? unfortunately the images in this mode can be said to be the maximum. In auto mode, the camera will determine the size of the ISO, Shutter Speed, Aperture workflow using the computer specified by the makers of cameras based on light conditions when we pressed the shutter half (do metering).

 

When we shoot the light a little tricky, at sunset, for example, the camera will be quite confused and produce images that do not describe sunset we wanted. anyway, you've bought a camera with DSLR / mirrorless more expensive than the tiny pocket camera or smartphone, continuous shooting with auto mode it feels really so wasteful.

 

Overall, a decent Auto Mode is used when the following conditions:

• when we are in a hurry, the important moments of his dapet, setting the camera does not trigger
• when you are really a beginner, do not understand the concept of exposure

 

In the latest generation of cameras, available Intelligent Auto mode, this is the auto mode with the addition of features such as face detection, i-Contrast (Canon) or D-Lighting (Nikon). There is also the name Creative Auto where we can change the depth of field. If your camera is equipped, use intelligent auto mode / auto's creative than regular auto mode, at least there will be an increase in the photos.

 

Please know that while in auto mode, many options and camera settings will be turned off by the camera to facilitate her work.

 

Scene mode

Scene mode selection mode is where we choose the type of object or scene to be certain that we photograph. Suppose we want to take a friend: turn the wheel to the position Scene mode and then we select Portrait. In Scene Mode, the camera is equipped with camera settings that are commonly used in typical shooting situations.

 

Here are some types of situations provided in scene mode:

• Portrait: the camera will automatically narrow the depth of field (dpeth of field) so that the background becomes a blur and made more prominent facial models (plus settings for softening skin tone and make your skin look smoother).
• Landscape: when we were photographing the scenery, the camera will use a sharp wide space so that objects close to the lens to the farthest look sharp. Green and blue colors will also be in the highlight
• Macro (Close Up): when you want to capture the interest of short-haul or want to take a bowl of meatballs before eating.
• Sports: we used when photographing fast-moving objects. The camera will move to focus tracking method to follow the movement of the object before.
• Night Portrait: used when we want to capture a face at night. Flash will automatically turn
• Sunset / Sunrise: simply explained, is used when we want to capture the sunset or sunrise
• Fireworks: to photograph fireworks by using a very slow shutter speed
• Beach / Snow: the camera will compensate to avoid under-exposed photo for measuring the white background Some other scene mode options depending on the type and brand of camera

 

Program Mode (P)

When in the Program Mode (P) camera will automatically determine the shutter speed and aperture settings. Even so, we can change the combination of aperture or shutter speed. The camera will try to balance between the shutter and aperture, if we direct the lens into the bright area, the numbers are automatically enlarged aperture while the shutter speed is maintained at the numbers pretty quickly. Point the camera at a dark area and aperture numbers will shrink to retain the shutter so that not too blur.

 

How to change the settings for the selected camera is by rotating the camera control wheel. If we turn the dial to the left then the camera will be "forced" to add slow shutter speed and aperture. If memuter dial to the right, the camera will be "forced" to speed up the shutter speed and aperture far.

 

Mode program in more detail are also discussed in this article.

 

Shutter Speed ​​Priority Mode (S or Tv)

In the shutter priority mode, we manually set the shutter speed and the camera automatically selects the aperture value based on the amount of light entering through the lens.

 

We can use this mode when the shutter speed is most critical settings: for example, when will freeze the motion of objects that move quickly (it took a very high shutter speed) or if we deliberately want to create a blurry photos (need a low shutter speed). Similarly, when we wanted to use techniques like panning photo below, move to shutter mode priosity will greatly facilitate the work:

 

When panning with this time of 1/10 sec, the shutter priority mode is used

If there is too much light, then the number will be enlarged aperture (lens opening narrowed) so that the amount of light entering the lens will be reduced. If too little light to enter the lens aperture numbers will shrink (aperture dilates) so that more and more incoming light lens.

 

So in shutter priority mode, shutter speed will be a constant value has not changed in accordance (according to the settings of us), while the aperture value will vary depending on the amount of light. Read also: 6 Technique Landscape Photography Creative Shutter Speed.

 

Aperture Priority Mode (A or Av)

In aperture priority mode, we determine the aperture settings manually and the camera will determine the shutter speed according to the amount of light entering the lens. By using this mode, we have full control over depth of field (depth of field), because we can decrease or increase the aperture and let the camera calculates the shutter speed.

 

Using aperture priority mode is a safer way to use the camera for photo risk under-exposed (darker) or over-exposed (too bright) in a rather small. Why? because the value of his camera shutter fairly wide range: from 30 seconds to 1/4000 second (or 1/8000 sec at certain camera), and a range of numbers as it is wide enough to light a variety of shooting situations.

 

To be in front of a puddle as sharp objects in the background, use aperture priority and set at f / 14
In order puddle looks as sharp front end of the bridge on the far side, aperture priority is used and set at f / 14

 

About the aperture priority mode, please read the article that discussed further herein.
 

Manual mode (M)

As the name suggests, we determine the aperture and shutter speed manually cameras entirely. The camera will only perform light measurements and make recommendations through the metering scale, but will not do anything other than that.

 

This mode can be used when photographing objects photo lighting conditions-it makes the camera "confused". An example is when we were photographing friends at the beach are very bright, the camera may misjudge the exposure so that the face of a black friend so that the sand on the beach is not over-exposed. In these conditions, we can use the manual mode, perform metering with spot metering to measure the exposure in the face of my friend and then sets the aperture and shutter speed manually based on the metering earlier. The result is a picture that is more concerned with the face of a friend, and subordinating its shores.

 

Manual mode is also useful when for example we are shooting the panorama, so happens consistency. Produced panoramic photos of some photos that were stitched, and the aperture value and shutter speed should always be consistent so that the final results will be consistent panorama photos are not mottled dark and there was no light. Examples of other uses are shooting sessions using various flash (flash) in the studio to be difficult to measure the camera's metering and requires lightmeter separately.

 

To change after the shutter speed and aperture, when you use the camera which has only one wheel control (command dial), the rotary control will change only one: the aperture or shutter speed. Other settings changed by rotating the control wheel while exposure compensation button pressed.
Bulb mode (B)

 

Bulb mode is one of the special setting of the camera, where we could use a shutter speed of 30 seconds, we can even use a shutter speed as long as we want. The maximum shutter speed range in DSLR cameras / mirrorless while using other modes will be stuck in the 30 seconds, now with a bulb mode we could use a shutter speed far exceed this figure.

 

The word bulb appears as the ancient times, our grandparents are becoming a photographer uses the wind bubble gum (bulb) which presses the shutter mechanism that opens.
Bulb mode is required to take photographs with a time sksposure 120s this.
Bulb mode is required to take photographs with a time of 120 seconds sksposure this.

 

What the bulb mode, how to use and examples of its use are discussed in this article.
 

Record Mode

That is the types of fashion that we can choose for the shooting conditions and different skill levels. No one will make fun of you because of more frequent use auto mode, auto mode but will limit the creative power that can be achieved with your camera. Who are accustomed to using auto or scene, try to turn it to A or Av, aperture priority, and the last was the one there all day. The majority of professional photographers spend more than 75% of their camera settings in the position of the aperture priority mode. Worth a try, and you will be amazed at your own skills.
