Crisp and Basic understanding on Photography - The aperture
Lets Understand the crisp and basic concepts of photography.
Photography is the science, art and practice of creating durable images by recording light or other electromagnetic radiation, either chemically by means of a light-sensitive material such as photographic film, or electronically by means of an image sensor.
Understanding Exposure : A photograph's exposure determines how light or dark an image will appear when it's been captured by your camera.
This is determined by just three camera settings: aperture, ISO and shutter speed. Mastering their use is an essential part of photography.
Aperture is one of the three pillars of photography, the other two being ISO and Shutter Speed.
Let us understand the first important camera setting aperture.
What is Aperture?
Aperture is a hole within a lens, through which light travels into the camera body or it is an adjustment of the lens opening, measured as f-number, which controls the amount of light passing through the lens.
In combination with variation of shutter speed, the aperture size will regulate the film's or image sensor's degree of exposure to light. Typically, a fast shutter will require a larger aperture to ensure sufficient light exposure, and a slow shutter will require a smaller aperture to avoid excessive exposure.
It is easier to understand the concept if you just think about our eyes.
Aperture either adds a dimension to a photograph by blurring the background, or magically brings everything in focus
In photography, aperture is expressed in f-numbers (for example f/5.6). These f-numbers that are known as “f-stops” are a way of describing the size of the aperture, or how open or closed the aperture is. A smaller f-stop means a larger aperture, while a larger f-stop means a smaller aperture.
Most people find this awkward, since we are used to having larger numbers represent larger values, but not in this case.
For example, f/1.4 is larger than f/2.0 and much larger than f/8.0.
In photographer slang, when someone says they are "stopping down" or "opening up" their lens, they are referring to increasing and decreasing the f-stop value, respectively.
One important thing to remember here is that, the size of the aperture has a direct impact on the depth of field,which is the area of the image that appears sharp.
A large f-number such as f/32, (which means a smaller aperture) will bring all foreground and background objects in focus, while a small f-number such as f/1.4 will isolate the foreground from the background by making the foreground objects sharp and the background blurry.
