ISO100, 1/250s, f/1.4 - See some real examples of aperture / shutter speed / ISO combinations.
- Shutter speed
- Should be faster than 1/50, if not use tripod to avoid shake
- 4 second(s) - 4.000,0 ms
-
4 sec short long exposure - Aperture
- f/2 - Very small DOF - Very fast lens
-
f/2 large (fast) small - 50mm lens: aperture diameter = 25,00mm
- Film speed/Sensitivity
- ISO 50 - Very slow film (Very sunny)
-
50 slow sensitive - Focal length of the lens
- 50 mm
50mm macro tele 
- Focal Length: 50 mm (analog) - 75 mm (digital SLR)
- Zoom: neutral zoom (1X)
- Picture angle: 46,8° (diagonal)
- Light conditions
-
This is an estimation of the amount of light that is present in your scene.
Low (wide) aperture, slow shutter, high ISO: it's probably very dark.
High (narrow) aperture, fast shutter, low ISO: it's probably very bright.
