* All elements of exposure work together. *

 

Comparison between shooting modes in the Basic Zone and Creative Zone.

  • This is for a Canon 350D (Rebel XT) however the same principals apply to other cameras.
  • Landscape Mode - Camera will automatically set ISO 100 to 400.
  • .................. Will always try to set the smallest aperture possible - Allowing greatest depth of field.
  • .................. However this may be at the expense of a slow shutter speed below hand holding ability
  • .................. Also The aperture May still be small enough to meet your depth of field needs.
  • .................. No use of the flash at all.
  • .................. And as always no control of the final output (.jpg pictures only)
  • Here are some pics showing typical landscape mode applications.
  • They are not taken in Landscape mode as I don't personally use it. They are vacation shots.

  • Here is a classic case where you may possibly want to use Landscape mode (I didn't).
  • The foreground tree framing the scene is relative sharp as is the fortress up on the hill, as well as everything in between.
  • That is because I used a relative small aperture (F20) to give us great depth of field.
  • Canon 350D (Rebel XT) with Canon 17-85 IS lens @ 26mm (~40mm)
  • ISO 400 1/125 @ F 20
  • Original image was shot in RAW format to give me more control
  • A larger pic is not available.
  • In Landscape shooting mode you cannot use a flash.
  • Here is what happens if you have a lot of light behind the subject.
  • The next photo will show what happens when you use fill in flash (Another tutorial?)

  • Because there is a lot of light coming in from behind me (in the picture) I am underexposed although I am relatively sharp as is the background.
  • Canon 350D (Rebel XT) with 17-85 IS lens@ 24 mm (~40mm)ISO 400 1/160 at F9 . No fill in flash.
  • No larger pic available.
  • If I am not in landscape mode I can use a flash with the results as below.
  • It is not perfect however it is a lot better than the picture above.
  • Now you can see me as well as the background. All is still relatively sharp because of the F9 aperture.
  • Canon 350D (Rebel XT) with 17-85 IS lens@ 24 mm (~40mm) ISO 400 1/200 at F9 .
  • The built in flash was used to fill in the missing details, ie: Throw a bit of light onto me.
  • I think was in Shutter Priority mode.... still to come in this tutorial
  • No larger pic available.
  • This is similar to using Night Portrait mode, however at night the camera may set a slow shutter speed to capture the background resulting in the background being un sharp due to ca mara movement.

Remember - Rule # 1 - Read the book! - the one that came with your camera.
