Essential Photography Tips
Use a wide aperture for portraits
Anyone with a cat knows that when they're hunting or playing their irises contract to enlarge the size of their pupils. This has the same effect as widening the aperture in a camera lens: it makes the subject they are focusing on very sharp while causing everything behind and in front of it to blur. We call this a shallow depth of field. This is perfect for portrait photography, as it draws forward your model within the scene, making them the central focus while the background falls away. Choose f/1.8 or similar wherever possible.This image of a chicken was taken with a wide aperture to keep the subject in focus while blurring the background.
