The Basics of Aperture

Lower aperture - Ravindra Joisa Photography

Many get inspired by looking at some of the great photographers work and is it always good to follow their work. Most of them just buy a camera and then press the shutter button (in Auto mode) to capture an image without understanding the basics of camera like aperture, shutter or ISO. The first thing that you need to do is go through each and every page in the manual and know what each and every button in your camera does. Understand the functionality because the menu in your camera has too many built-in options and features. Next is to understand the basics of photography.

In this article I have written about aperture. Aperture is nothing but the size of the opening in your lens through which the light goes to your image sensor, this can be varied by opening or closing a set of diaphragm blades within the lens to make the final picture. Wider the opening, more is the light allowed. Example: f2.8 is an aperture which is wide open and can be used when there is low light. It also makes the background blur as shown in the above image. A small opening of diaphragm blades allows less light. Example: f22 is an aperture with narrow opening and doesn’t allow much light to pass through the lens. This is good to use when there is too much light on a bright sunny day (approx. f11) or for a long exposure shot during day time. These kind of settings are used in landscape shots where you want everything in focus as shown below.
