Photo HDR (High Dynamic Range) is a photograph obtained by combining several images with varying tones so as to produce an image that has particularly tonal range beyond the original capabilities of the camera. Before it can be processed, we have to make some raw images that have a different exposure, the number of images required is between three to five pieces. Here are practical steps:
1. Because we will combine multiple photos at once, use a tripod so that the results are sharp and no ghosting
2. Set the camera in aperture priority mode (A or Av), with this mode you select the aperture and the camera was the one who 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 manual focusing mode
4. Set automatic bracketing on the camera to produce 3, 5 or 7 fruit photos with shutter speed varies (Nikon & Canon, for other cameras please see the manual):
Nikon SLR:
- Click on the Fn key (bottom position in advance)
- Rotate the command dial behind the camera until we see a sign on the LCD above bracketing
- Select five bracketing (or 3, 5, 7 or to taste)
- Change position on a continuous release mode high speed
Canon SLR:
- Click and hold the Mode button and AF.Drive to activate bracketing
- Set of 5 in the Custom Functions menu (or 3, 5 or 7, according to taste)
- Set the camera in burst mode
- Begin taking exposure
- For processing we are able to use special software such as Photomatix Pro for HDR – (free demo version) or do it in Photoshop
