Aperture changes two elements within an image. Aperture controls depth of field in the photograph and also how much light is exposed.
Aperture is defined by f/stops. E.g, f2.8 f.11
To set aperture on the camera you change the settings to A.V (Aperture Value) and then you can use the wheel to change the number. Numbers such as f2.8 have more light and have a faster shutter so are less sharp.Numbers such as F.11 have less light and a slower shutter speed so are more sharp.
When would you use a aperture greater than f5.6?
- LANDSCAPES, TIMELAPSES, LIGHTING
When would you use a aperture lower than f4.5
- SPORT, GIGS
