EASY STEPS TO SETTING UP HDR PHOTO

Posted at 8:50 PM by Unknown
HDR IMAGE
HDR Photo (High Dynamic Range) is images are obtained by combining several images with varying tone to produce an image that has the tonal range beyond the original capabilities of the camera.

Before it can be processed, we have to make some raw images with different exposures, the number of images required is between three to five pieces. Here are practical steps:

  1. Since we will mix up multiple photos at once, use a tripod so that the results are sharp and not shaded
  2. Set the camera in aperture priority mode (A or Av), with this mode you select the aperture and the camera was the one that determines the shutter speed
  3. Set focus on the position of the manual focusing. Try some snap to determine the focus in autofocus mode, after we set the focus, change the focusing mode to manual
  4. Set automatic bracketing on the camera to produce 3, 5 or 7 pieces of images with varying shutter speed (Nikon & Canon, for other cameras please refer to the manual):
Nikon SLR:

        Push the Fn button (position in the face of the bottom)
        Rotate the rear command dial until we see a camera in the LCD above bracketing
        Choose five bracketing (or 3, 5, 7 or to taste)
        Change position on the continuous release of high speed mode

    Canon SLR:

        Push and hold the Mode button to activate bracketing and AF.Drive
        Set Custom Functions 5 in the menu (or 3, 5 or 7, according to taste)
        Set the camera in burst mode

  1. Begin taking exposure
  2. For processing we could use special software such as Photomatix Pro HDR - (free demo version) or do it in Photoshop ... click here for steps to HDR in Photoshop

    Note: the choice of how images are used depending on our needs exactly. Three photos in Photoshop will make the process much faster than 5, but if we have 5 pieces of the final image produced will have a smoother tonal.
