- 4. What is shutter speed? It is essentially the 1/8000,indicator of the1/4000,duration / timing 1/1000,at which the 1/500,shutter curtain 1/250,opens up and 1/125,closes during an 1/60,exposure process 1/30, 1/15, 1/8, 1/4, 1/2, 1 etc.
- 5. Shutter speed dial The shutter speed dial provide the selectionof shutter speeds, and indicates the timing ofthe shutter open and closes. A fast shutter speed such as 1/500 sec willclose faster than, say 1/2 sec exposure time.In this case, the shutter curtain will close veryfast and thus resulting in less light enteringthe film.
- 6. What does shutter speed do ? Different shutter speeds yield different kind ofvisual effect on a final photograph. A fast shutter speed can freeze actionwhile slow speed can blur your image

- 12. Aperture By: Amit Chawla
- 13. What is Aperture? The aperture is like a pupil in your eye. The pupilopening is bigger in a room with less light to allow youto see and Vice Versa. In Photography, Aperture is referred to lensdiaphragm opening inside a photographic lens. The size of this diaphragm opening in a camera lensREGULATES amount of light that passes through ontofilm inside the camera. The size of an aperture in a lens can either be a fixedor adjustable type (like an SLR camera).
- 14. How is aperture calibrated ?Aperture size is usuallycalibrated in f-numbers. Theseare ratios. i.e. f 22 (f/22), f16 (f/16), f/11, f/8.0, f/5.6, f/4.0, f 3.5 ,f/2.8,f/2.0, f/1.8 etc.
- 15. What it means is f/16 will let in 1X the amount of light than adiaphragm opening of f/22 and so forth; f/4.0 will let in 1X lesser than that of f/2.8 etc. Aperture + Shutter Speed = Exposure Aperture, along with duration/timing of shutter curtainopening, BOTH contribute to a the formation of anexposure. Aperture also affects "depth of field"
- 16. Exposure Balancing Shutter and Aperture:Exposure is about different combinations ofshutter and f-stop settings. Thesecombinations can drastically affect thefinished picture.
