Exposure is the amount of light a digital camera’s sensor captures when a photo is taken. If you capture too much light, the results are a washed out photo or what is commonly referred to as overexposed. If you capture too little light, the photo will be too dark or underexposed. There are three settings that directly affect exposure; Aperture, Shutter Speed, and ISO. These settings not only affect exposure, they also allow you to control how each photo will look.
In order to construct proper exposure, you will need to understand the above mentioned Aperture, Shutter Speed, and ISO. Once you understand these key items, you will be able to handle any situation with ease.
Let’s start with Shutter Speed.
