ISO Balance

 Shutter Speed: The shutter speed is how long the shutter is open when an image is taken. The longer the shutter is open the more light will get in and the brighter the image will be. The shorter the shutter speed the less light gets in and the darker the image will be. A slow shutter speed will give motion blur, while a higher shutter speed will give the appearance of an object being frozen in time.




Aperture: The aperture is how large the opening in the lens is, the higher the f stop the lower the aperture and the lower the f stop the higher the aperture. The larger the aperture is the smaller your depth of field will be, and the smaller the aperture the larger your depth of field will be. Portraits and night shots require a bigger aperture. A smaller aperture would be used on a bright day or when taking landscape shots.



ISO: The ISO measures the sensitivity of the image. The lower the ISO the less sensitive it will be and the less light it will sense. The higher the ISO the more sensitive it will be and the more light it will sense. The higher your ISO is the more noise will be in your image, but will also allow you to use faster shutter speeds to avoid motion blur.
