Exposure compensation is a function that allows the photographer, the ability to adjust the exposure to compensate for situations in which the measuring system of the camera did a poor job.
That would be something you want to make adjustments in the light of contrast, when it would otherwise be lost highlight detail, or when shooting landscapes or other scenes delicate snow. The picture accompanying this post is a good example of a real life situation .. Photography learning water breaking was very bright and the karate had a helmet on which projects a very dark shadow on the face. I had to use my exposure compensation to make sure I have not jump out of the water, or the dark side photography learning. It took a couple of photos to get the correct settings, but it was worth photography learning.
The cameras are scheduled to address only half the grayscale ... A camera exposes the luminance value center stage (medium gray, 12-18% reflectance or 50% brightness) and its various ways of measuring chambers are just different ways of placing the weighted average value in meters the camera photography learning .
EVE Compensation solves this problem by saying the camera to expose a building is more or less what he thinks is right photography distance learning . Photography distance learning For very bright settings (such as snow or on the beach), define a value as a positive number EVE (1/3 1, etc..) For very dark scenes, choose a number of negative EVE.
Now I know what you're thinking - it makes no sense! If the reason is very clear, I do not need EVE down (negative value) to make sure that the image is properly exposed?
Well, no. This is the opposite. It helps to think about what the resulting image will look like. In the snow, where there are many bright areas, the camera selects a midpoint in the free zone, so that the snow is gray in the resulting image photography learning. Photography distance learning To solve this problem and make the white snow (as they should), it is necessary to clarify the picture. Therefore, we have to increase the exposure and use a positive number photography learning .
You should consider using exposure compensation in the following situations:
Landscape photography in bright and sunny - landscapes are shot wide angle (zoom) and often has a bright sky and dark shadows. The estimate of the average value in this type of situation often contrasting your camera can cause important details to note is that is lost in the sky because of the bright orange ball of light photography learning, also known as the sun. To remedy this photography distance learning , you would darken the image slightly reducing exposure photography learning , usually two or three stops
learning digital photography. This lightens the shadows and put these awesome colors back in the sky that attracted you to the image in the first place photography learning.
Snow scenes - scenes are exceptionally white snow learning digital photography , and the camera will think that is supposed to be closer to medium gray photography learning. Without adjusting your white fluffy snow comes the pale blue ... Sound familiar? To remedy this, you want to brighten the image learning digital photography , increasing the exposure to 1 or 1 EVE 1/3rd photography learning .
Most cameras have a screen EVE (in the viewfinder or on the screen). Zero in the center is where no compensation applies EVE, left us-EVE and right, that EVE +, with middle 1/3rd EVE photography learning.
Depending on the camera and setting up the display device photography learning,
learning digital photography the display can show EVE during use or when compensation has been applied photography learning.
In aperture priority, shutter priority or Programmed Auto
Locate the camera's EVE button (labeled or EVE + / -) photography distance learning , learning digital photography hold and scroll wheel corresponding command is + right or left, depending on whether you want to increase or decrease the exposure (lighter or darker image) photography learning. Learning digital photography When you scroll, the marker will move with the corresponding value in the scale value of the screen or just the screen updates only type photography learning.
Do not forget to adjust the EVE restart once you have finished taking pictures with exposure compensation photography learning , learning digital photography.
Manual Exposure learning digital photography
In manual mode, you can select the shutter speed and aperture, and EVE screen tells you how much you can be different from the count of the camera suggests. The EVE button is not used, but the effect of the exposure is the same photography learning.
The advantage with exposure manually applied is that you do not have to think about how to reset the compensation. However learning digital photography, you have to set the exposure for each shot photography learning.
