Camera focus: Types and Functions

Image
For a photograph be good and presentable, arguably the most important thing that must be maintained is a sharp focus on whatever subject is within the frame. This blog post will be a guide to learn about the focus modes and functions that a camera has, and how to properly utilize them to take a sharp photo. Focusing in a camera can be done by either  manual focusing , which involves focusing on the subject by adjusting the focus ring on the lens manually, or by  autofocus , where the camera detects the subject in the frame and adjusts the lens to get the sharpest image.

The Exposure triangle Exposure is how much light per unit area is reaching the plane surface of an image sensor i.e. the amount of light the image sensor is being exposed to. Exposure of an image depends on four elements viz. ISO, aperture ,  shutter speed  and luminescence of the scene. And out of these four elements, most of the time only 3 can be controlled (unless you're in a studio 🤷)   viz . ISO, Aperture and Shutter Speed . These three elements constitute what is known in photography as the Exposure triangle In my previous blog post , I mentioned ISO, aperture and a little bit about shutter speed. This blog post will further elaborate on how they specifically affect a photo. 1. ISO As mentioned before, ISO is the sensitivity or receptivity of the imag...

In this blog post, I will share the things I think are important and worth considering before buying a camera. 1. Image sensor Photo by Alexander Andrew on Unsplash Image sensors are the part of camera that captures the photo by converting light (photons) into electric signals (electrons) . This is one of the most important features of a camera as it will directly affect the photos you take. To put it simply, there are three sizes of camera sensors that are available to the consumer market viz. Full frame , APS-C and Micro four thirds . The price of the camera also depends on the sensor size. A ful...
