Exposure Iso Aperture Shutter Speed

Exposure Iso Aperture Shutter Speed. Digital Photography. Exposure. Exposure is the amount of light a digital camera's sensor captures when a photo is taken. Too much light results in a washed out photo (overexposed). Too little light and the photo will be too dark (underexposed).

  2. Exposure • Exposure is the amount of light a digital camera's sensor captures when a photo is taken. • Too much light results in a washed out photo (overexposed). • Too little light and the photo will be too dark (underexposed). • You can control exposure with three settings: • ISO - sensitivity of your camera's sensor to light • Aperture– size of the opening • Shutter speed – duration of shot

  3. Aperture • The aperture is a small set of blades that are located in the lens; this controls the amount of light. • Measured in F-stops • F stands for focal length • F-stop is the focal length divided by the diameter of the lens. • For example, a 200mm f/4 lens will be 50mm wide. • You can measure it. 200mm/50mm = f/4. • That is why f-stop is typically written as F/4, meaning "focal-length divided by four". • https://Understanding aperture

  4. Aperture • Low f/stops • large openings, more light, shallow DOF. • Higher f/stops • smaller openings, less light, deep DOF.

  5. Shutter Speed • Shutter speed – the duration for which the shutter is open. • Shutter speed is measured in seconds– or in most cases fractions of seconds. • The bigger the denominator, the faster the speed (i.e. 1/1000 is much faster than 1/30). • Fast shutter speeds freeze motion • Slow shutter speeds blur motion

  6. Controlling Shutter Speed

  7. Exposure Triangle Explained • http:Understanding the exposure triangle

  8. Manual vs. Automatic • Look at the two pictures below; same photo - different camera settings. Automatic Exposure Manual Exposure

  9. Exposure • The beauty of the image stems from drawing attention to the sunset, not the bird. • You cannot accomplish this in automatic mode.

  10. Composition and DOF • Compositionis the placement or arrangement of visual elements in a work of art. • Identifying and learning how to control composition is key to developing an amazing portfolio. • One of the basic elements of composition is “Depth of Field” • DOF refers to how much of the picture is in focus.

  11. Personal Preference • DOF is commonly used to draw attention to a specific part of the photograph. • Shallow DOF • Deep DOF

  12. Shallow Dof - a portion of image is in focus.

  13. Shallow DOF

  14. deep DoF - the whole image is focused

  15. deep DOF

  16. Control ling f-stop! What happens as the f-stop increases?

  17. Camera Settings • Set your camera to “Aperture Priority” (A or AV) • This setting will allow you to change your aperture but will automatically control your shutter speed and ISO. • http://www.youtube.com/watch?v=l3zdybilbCY

  18. For a Shallow Depth Of Field • Decrease f-stop (Lens opening will be big) • Decrease distance from subject • Decrease ISO setting (only if using manual) • Increase focal length (zoom in)

  19. For a Deep Depth of Field • Increase f-stop (Lens opening will be small) • Increase distance from subject • Increase ISO setting (only if using manual) • Decrease focal length (zoom out)
