Shutter Priority Auto Exposure (T, TV, S)

Shutter priority auto exposure (T, TV, S) is used primarily to specifically check exposure. This mode is especially effective if consecutive images need to be checked.

Use

  • This mode is used primarily to specifically check exposure
  • Especially effective if several consecutive images need to be checked for exposure - for just one image see program mode auto exposure and program shift
  • Camera settings need to be checked

 

Use, possibilities and problems

  • In this mode, the photographer can preselect the exposure time
  • The camera selects (from the available diaphragms) the diaphragm to achieve an optimal exposure
  • Fast shutter speeds allow a sharp image of motion to be captured (in addition, the risk of blurring is low)
  • Slow shutter speeds allow a blurred image of motion to be captured (e.g. motion blur)

Important – Checking camera settings

  • Check camera display
    • If the required exposure time for the correct diaphragm exceeds the camera’s technical lens settings, this is indicated in the camera’s viewfinder (dependent on type of camera and manufacturer – shutter speed usually flashes – check user’s manual!)
       
    • The desired shutter speed setting can potentially be achieved by changing the ISO settings (if the required shutter speed exceeds the camera’s technical lens settings, the ISO rate can potentially be decreased or increased)
  • Additionally, be careful as the risk of blurring is higher if the shutter speed is too fast

 

In this mode, just like in the program mode auto exposure, all camera settings need to be checked.
