What do you need to know about photography?

Basic photography concepts are aperture, shutter speed and ISO or what we call the exposure triangle. Photography is all about light, in order to make an awesome output you must know how to control how much light is needed to reach the camera sensor.

Aperture

Aperture refers to the opening of a lens’s diaphragm through which light passes. It is calibrated in f/stops and is generally written as numbers such as 1.4, 2, 2.8, 4, 5.6, 8, 11 and 16. Lower f/stops give more exposure because they represent the larger apertures, while the higher f/stops give less exposure because they represent smaller apertures.

The larger the opening more light passes through and the shallow the depth of field occurs behind the subject, or in other terms it’s called Bokeh. Yes, you guess it right. The smaller the opening the less light passes through and the more focus and deeper depth of field occurs.

Shutter Speed

Shutter Speed is basically the duration of the shutter being open. Exposing light onto the camera sensor. It is really important to have the right shutter speed at the right time of the day, specially shooting outdoors.

If the shutter speed is at the lowest or slow value it allows more light to pass through the sensor, but the output will be shaky and blurry handheld so it is really recommended to use a tripod in this state. If the shutter speed is high or fast it allows less light to pass through the sensor, there’s no need to worry about blurry at this state because it freezes action and you can shoot handheld.

ISO

One of the most confusing settings is ISO, which is one of the factors of the Exposure Triangle , along with shutter speed and aperture.  ISO is basically the sensitivity of the sensor to absorb light.

The lower the ISO value the darker the output can be, the higher ISO the brighter the output can be. But the thing is once the ISO is getting higher the more image Noise/Grainy the output will be.
