Aperture is like the “pupil” for your camera system, which can open and close to change the amount of light that passes through. Note the nine blades in this lens, which form a diaphragm to block any light that tries to pass, except through the center.. The technical definition of aperture is: “The opening in a lens through which light passes to enter the camera.”

Aperture is one of the three factors that create an exposure.Understanding the aperture settings makes getting to grips with taking an evenly exposed photo a lot easier.

In photography, exposure is the amount of light per unit area (the image plane illuminance times the exposure time) reaching a photographic film or electronic image sensor, as determined by shutter speed, lens aperture and scene luminance.Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance in a specified region.

You may have heard that f/16 is the go-to aperture to use for landscape photography. But there are a few factors you'll want to consider before making that choice - let's have a look.

It is difficult to take good pictures without having a solid understanding of ISO, Shutter Speed and Aperture – the Three Kings of Photography, also known as the “Exposure Triangle“. While most new DSLRs have “Auto” modes that automatically pick the right shutter speed, aperture and even ISO for your exposure, using an Auto mode puts limits on what you can achieve with your camera.

Equivalence relates the visual properties of photos from different formats based on the focal length and aperture of the lens. Neither the focal length nor the relative aperture of a lens change as a function of sensor (for example, a 50mm f/1.4 lens is a 50mm f/1.4 lens, regardless of the sensor behind the lens).

Numerical aperture is not typically used in photography.Instead, the angular aperture of a lens (or an imaging mirror) is expressed by the f-number, written f / or N, which is defined as the ratio of the focal length f to the diameter of the entrance pupil D: =. This ratio is related to the image-space numerical aperture when the lens is focused at infinity.

The main component of the creative approach to portrait photography is the use of digital software. The creative approach requires that the photographer take the portrait in a traditional fashion ...
