HDR is an acronym for High Dynamic Range. HDR brings out the deepest shadows and the brightest highlights of a scene. In most cases, this process needs at least three images. The first one is to capture a mid-range exposure shot. Meanwhile, the second meter for the highlights, and third for the shadows. Ways to achieve this:

  • Set your camera to save the photo in RAW and to manual mode ;
  • Use the lowest ISO setting to work for your situation. Increasing the ISO will reduce the DR the sensor can record.
  • For three images, the values should be 0, +3, and -3. +3.For seven images, your range should be -3, -2, -1, 0, +1, +2, +3.
