HDR- more than 3 photos? EV range.

[Brian Cluff]

An extreme example: Imagine that you are trying to get a good picture of 
someone arc welding at night outside.  You would need to at least take a 
picture of them fast enough so that the light from the arc doesn't 
obliterate everything else in the picture, and then you would need to 
get a picture slow enough so that it could capture everything that isn't 
being lit by the light of the welder, then you would need to take a 
normal picture to pick up everything that is at a normal light level.

In the above example you will be taking pictures at the extreme ends of 
your camera's exposure limits in order to get a proper spread of images 
for your HDR and your camera probably won't allow enough spread to do it 
automatically since the image to covert the dark parts may require a few 
seconds of exposure to properly expose the darker parts of the image.
