9.2.f. HDR:
The HDR mode will take pictures with different exposures automatically, so you
can later combine them to make an HDR photo. This mode is based on three
parameters. These are Center, EV(+-) and Frame. HDR mode takes pictures in odd
numbers (3, 5 and 7). The photo in the middle of the sequence (respectively 2nd,
3rd, and 4th) will have the center exposure value. The other photos will have
changing exposures starting from the lower end up to the higher end. The other
exposure values are calculated with the number of stops between each frame per
the total frame number.
Warning: The HDR functionality is provided with the BULB mode of the camera.
The camera must be in BULB mode; otherwise, all of the photos will have the same
exposure. The shutter speed you can achieve over the shutter release port is
limited. In most cameras, you cannot get faster than 1/30th of a second from the
cable release port. Because of this limitation, some EV(+-) and Frame values will
be disabled for some Center values.
