In this mode, the shutter stays open as long as you hold down the 
shutter button completely, and closes when you let go of the shutter 
button. This is called bulb exposure. Use bulb exposures for night 
scenes, fireworks, astronomical objects, and other subjects requiring 
long exposures.

Highlight detail and shadow detail are retained for a high dynamic range 
of tones even with high-contrast scenes. HDR shooting is effective for 
landscape and still-life shots.
With HDR shooting, three images of different exposures (standard 
exposure, underexposure, and ov erexposure) are captured for 
each shot and then merged together automatically. The HDR 
image is recorded as a JPEG image.
* HDR stands for High Dynamic Range.

 Only the merged multiple-exposure  image will be saved. The images 
taken in steps 6 and 7 for the multip le-exposure image will not be saved.
  With multiple exposures, the more  exposures there are, the more 
noticeable the noise, irregular colors , and banding will be. Also, as noise 
increases with higher ISO speeds,  shooting at low ISO speeds is 
recommended.
