Simply put, for landscape pictures a high F-number like F11 (closed) setting is used while an extreme close up might use an F4 setting.Shutter speed is measured in seconds (1/500. 1/250. 1/100,1/2, 1 etc.) or even a setting to hold the shutter open indefinitely. The extremes are obvious, a fast speed for action shots and very slow for a night picture, the rest is best learned by experience and experimentation.
