Because bodies like the D800 and D4 can shoot 9 shot
brackets, and in High Speed Continous mode the camera
can be set to stop at 9 shots, it is easy to actually
bracket at +/- 4 EV with those cameras. And that is a
greater spread than the D600 can get shooting three
shots with 3 EV steps.

I don't think the D800 shoots faster than the D600... and I don't think the D4
is 3 times faster than the D600... you're a little optimistic!

Who said anything at all about faster?

Was the reference to using "High Speed Continuous" a
cause of confusion? That merely provides the fastest
rate that the camera will shoot, whatever it happens to
be. (The fastest rate possible is better in order to avoid
any change is the scene during the time a set of exposures is
taken.)

The camera can be configured for the maximum number of
shots that will be taken with a single press of the
shutter button in a continuous mode. Hence, if the
bracketing is set to a specific number of shots,
regardless of the size of the step per shot, and the
camera is in a Continuous mode with a maximum number of
exposures that equals the number set in backeting... a
full bracketed set is automatically made with a single
press of the shutter release button.

The point made was that the D4 and D800 can be set to
shoot 9 shots with each 1 EV apart. That provides an
automatic bracketed range of +4 EV to -4 EV. That
cannot be done with the D600. It can be set to 3 shots
at most, and with each at most 3 EV apart, providing
only +3 EV to -3 EV.


Uhm! 3 x 3 =9, the last time I looked at a math table.


Uhm, you need more coffee and less of whatever it is you are doing.

Shot Count: 1 2 3
fstops : -3 0 +3

Three shots is two intervals from the first to the last.

For the D4 and similar models,

Shot Count: 1 2 3 4 5 6 7 8 9
f/stops : -4 -3 -2 -1 0 +1 +2 +3 +4


You have just proved my original point. Three shots are
adequate fpr HDR, if you have at least 2EV for each stop.
Go shoot some HDR and look at the results. Under most
circumstances you do not need more than a 4 EV spread.


You just proved you are still running around in circles
trying to find something that you can talk about with
some sembalance of sanity...

Who cares if you think 3 shots are adeqate, or if you
think it takes 4, or only 2. That was never the point,
and that is never going to be the point.

And what has that got to do with your silly 3*3=9 bit of
idiocy? Did your math book fail you again?
