What is the Minimum Aperture Number of the Sony Cyber-Shot DSC-WX300?
In photography, the aperture number refers to the size of the hole in the front of the camera lens, through which light is let through. The larger the aperture, the more light can pass through into the camera's sensor. Photographers can modify this aperture to control the 'depth of field' for their shot - this is how much of the shot is held in focus, and how much is blurred. Aperture numbers are measured in f/stops: rather confusingly a smaller aperture number translates to a larger hole, therefore a larger amount of light will be let through.
A smaller aperture number means that the camera's lens will be able to open wider, letting in more light at once. This is helpful because it allows the camera to quickly take in enough light to form a picture, meaning that the shutter speed will be faster, reducing blur from fast moving subjects. It also means that you can take photos in dimmer light without having to rely on the flash, since you will be able to take in more light at once.
