Number of compact digital cameras come with an auto-bracketing feature. When enabled, the camera shoots three frames in succession with different exposures—under, optimal and over. These photos are then combined into a single HDR photo with optimal lighting in the entire frame. Some cameras such as the Sony NEX-5N and Canon PowerShot S100 have the HDR function built-in. If your camera doesn’t feature HDR mode, you can use the bracketed shots to process the HDR shot manually. Adobe Photoshop or free tools such as easy HDR or Luminance HDR can be used for this.
