HDR Tutorial

What is HDR?

HDR or High Dynamic Range is a post processing task that requires you to take either one or series of images, combine and adjust its contrast ratio to create an image that are virtually impossible with a single aperture/shutter speed.

A common HDR image usually took three photos of the same scene with different Exposure Value. The results show bright, normal and dark photo based on the amount of light that got through your lens. A post processing software will then combine all photos to bring the details to the shadows and highlights both. HDR help us to achieve the same task in the final photography that our human eye can accomplish on the scene.

Tips on Shooting HDR

  1. You will need a good DSLR Camera
  2. Sturdy Tripod
  3. CamBuddy Pro - Joopic App (HDR Function)
  4. Adobe Photoshop or some other image-editing tool
  5. Watch out for wind – too much of it will move bushes/grass/trees, which will screw up your final image.
  6. Watch out for other moving objects as motion is difficult to fix in the software processing.
  7. Shoot frames quickly in bursts, especially if you have clouds in the frame.


Shutter release cable is necessary for this feature to work properly. Please connect the shutter release cable to trigger your camera shutter.

HDR features on cameras

HDR is also available in DSLR camera settings: Camera settings


  • Easy and efficient access to HDR effect photos


  • Transition range of EV value is large, therefore it is not accurate.
  • The default setting for number of shooting is 3 photos then combine into 1 HDR image. You cannot increase or decrease the number of shots.
  • The default variable is only the shutter speed. Other parameters such as ISO or Exposure value cannot be changed.
  • The default effect of gray scale is too large, it is not the ideal effect.
