What is Exposure?
Exposure is how light or dark an image is. An image is created when the camera sensor is exposed to light—that’s where the term originates. A dark photo is considered underexposed, or it wasn’t exposed to enough light; a light photo is overexposed or exposed to too much light. Exposure is controlled through aperture, shutter speed and ISO.
What is exposure Metering?
Metering is actually based on a middle gray, so having lighter or darker objects in the image can throw the metering off a little bit. Metering modes indicate how the meter is reading the light. Matrix metering means the camera is reading the light from the entire scene. Center-weighted metering considers only what’s at the center of the frame and spot metering measures the light based on where your focus point is.
What is Exposure Compensation?
Exposure compensation is a way to tell the camera that you’d like the exposure to be lighter or darker. Exposure compensation can be used on some automated modes and semi-automated modes like aperture priority. It’s measured in stops of light, with negative numbers resulting in a darker image and positive ones creating a brighter shot.
Which exposure setting to use for beginners?
When you first get a new camera, I would suggest starting with the Program Mode setting (P) which is located on the top of the camera. It’s a round dial with a series of Letters and Icons on top of it. Program is good to start with because the camera will look after all the exposure settings for you, but you can over ride it if needed. Unlike the Green AUTO setting (shown as a green rectangle), which is totally controlled by the camera.
Which exposure setting is best for sport?
Your best option for sports photography is either selecting the Sports icon on the Mode dial, or choosing the (S) or (TV) option otherwise know as Shutter Priority. This setting allows you to choose the shutter speed, while the camera looks after the Aperture setting.
Which exposure setting is best for Landscapes?
Here your best option for landscape photography is to choose between the Landscape icon on the Mode dial, or choose the (A) option otherwise know as Aperture Priority. This setting allows you to choose the Aperture opening, while the camera looks after the Shutter speed settings. Why choose Aperture priority, because it controls the Depth of Field (DOF) in your photographs, this allows you to have a photo that is in focus from front to back.
When to use the Manual exposure mode?
Manual exposure mode is unlike any other exposure setting, that is because it is totally set by yourself. When to use it? Manual exposure is general used by keen amateurs and professionals who want total control over their exposures. This is because your cameras metering system can be fooled by excessively light or dark situations, creating more unwanted work in the post-processing process.
What is the Exposure Triangle about?
When you start using just Manual exposure mode you will need to become very confident setting your Shutter, Aperture and ISO settings. The exposure triangle explains the relationship between the three controls. Basically, when you start changing one of the Shutter, Aperture or ISO settings, you have to compensate with one of the others. Importantly you need to refer to the builtin Light Meter in your camera to achieve an accurate exposure.
