Photography, or rather, digital photography seems to have become a way of life. Today, about 2 billion photos are uploaded every day to various sites like Flickers, Facebook, Instagram, and many others. Imagine that - 2 billion uploads on a daily basis! Wow! What if you know that you can start shooting photos or selfies that are really appealing to the eyes, and you can do just that without having necessarily to buy or use any of the expensive cameras and equipment? Well, here’s the good news! The truth is you can! In this deck, you will learn about the most basic (which is also most important) concepts of digital photography. Once you begin to grasp these fundamental ideas, you can really start getting creative on improving the aesthetics of your photos (while your friends can start marveling over what they see.)

When you change the aperture value, you are actually varying the amount of light passing through the lens. ‘ Aperbure Lens

I80 is the level of sensitivity of your camera to available light. Image source - Imp: //www. wired. co. uk/ news/ archive/2013-08/2/lighbmoves-hydrogels/ viewgallery/306811
I80 stands for Ii~! TERlvIATl0l~IAl 0IlllAl»! |ZATlflI~! ron STAl»! DARDlZATlul»I - the main governing body that standardizes sensitivity ratings for camera sensors.
The component within your camera that can change sensitivity is called “image sensor” or simply “sensor”.

The higher the number, the more sensitive your camera is to light.
lower I80 (full, 200) is good when you are shooting in bright day light
When you have less light (i. e. darker surrounding), you will raise the I80 up (400, 800, I000) to compensate.

Shutter speed is the AMO0NT 0F TIME the shutter remains opened.
In other words, it’s how long or how much time the aperture is opened. Image source - http: //www. ifans. corn/ forums/ Ihreads/ camera-shulter<anima(ion-is-hashed-up.388713/
