EXPOSURE TRIANGLE: APERTURE, ISO & SHUTTER SPEED Each setting controls exposure differently: Aperture: controls the area over which light can enter your camera. Shutter speed: controls the duration of the exposure. ISO speed: controls the sensitivity of your camera's sensor to a given amount of light.

Aperture priority, often abbreviated A or Av (for aperture value) on a camera mode dial, is a setting on some cameras that allows the user to set a specific aperture value (f-number) while the camera selects a shutter speed to match it that will result in proper exposure based on the lighting conditions as measured by ...

rarmstrong. Sunil, you are correct about the difference between AF and metering. The camera's metering system is taking readings of the specific point you have focused on and set the aperture and shutter speed to get the best exposure. When you move the camera, what it "sees" in terms of light from the scene, changes.

Shutter speeds available to you on your camera will usually double (approximately) with each setting. As a result you'll usually have the options for the following shutter speeds – 1/500, 1/250, 1/125, 1/60, 1/30, 1/15, 1/8 etc.

Auto Exposure Bracketing (AEB) ... This is called AEB (Auto Exposure Bracketing) shooting. You can set your camera so that the shutter speed and aperture value are changed automatically to capture three successive shots with exposure bracketing of ±5-stops in 1/3-stop increments.

To get your photos looking their best, you need to master the three basics: Aperture, Shutter Speed and ISO. You also need to understand the relationships between these three controls.

What does ISO on a camera stand for? ISO stands for the International Organization for Standardization — an organization that sets international standards for all different kinds of measurements. But, when in reference to your camera, the ISO is your camera's sensitivity to light.

An f-stop is a camera setting that specifies the aperture of the lens on a particular photograph. It is represented using f-numbers. The letter “f” stands for focal length of the lens.

The relationship between wavelength and numerical aperture is valid only for increased resolving power when light rays are parallel. Therefore, the resolving power is dependent on another factor, the refractive index. This is the bending power of light passing through air from the glass slide to the objective lens.

What is the Exposure Triangle? In photography, the exposure triangle explains the relationship between shutter speed, ISO and aperture. Whether you're shooting old school film or with a mirrorless, these three factors are at the center of every exposure.

The lens aperture is a diaphragm that is in the lens itself or immediately behind it. ... IMPORTANT: Changing the aperture also affects the depth of field . Shutter speed. Shutter speed also can affect the amount of light that comes into the camera by controlling how long the camera shutter remains open.

Compared to a full frame camera the GoPro has an aperture of f15. 8 and a focal length of 16.5 mm. The wide angle can be a limitation.

Wikipedia describes shutter speed as being the amount of time a digital cameras shutter is held open for when taking a photograph. Shutter speed allows light to reach the cameras image sensor.

It is the sensitivity of the film. Film speed is determined by an ISO number (in the UK/US this used to be known as ASA). ... A low ISO number will mean it's a slow film and is less sensitive to light. The higher the number the faster the film and the more sensitive it is to light.

Shutter, in photography, device through which the lens aperture of a camera is opened to admit light and thus expose the film (or the electronic image sensor of a digital camera). Adjustable shutters control exposure time, or the length of time during which light is admitted.

So really, image stabilization is the most important in situations where you don't have enough light to get a fast shutter speed. It tends to come in handy at sunset, sunrise, and indoors. In most cases, image stabilization will give you the same image quality at 3 to 4 shutter speed stops slower than usual.
