As begginer to the digital photography some terminology will be used and consider to get quality image. Most of them is Aperture, Shuterspeed and ISO this three will be helpful to the photographer if fully understand. But now let us focused on aperture.

Aperture of the lens- adjustment of the iris, measured as f-number which control the amount of light entering the lens. Aperture also has an effect on focus and depth of fields,namely, the smaller the opening ( aperture), the less light but the greater depth of field- that is, the greater the range within the object appear to be the sharply focused.
