That works for daylight.Just for curiosity, why you bracket?
And little explanation why asked, I've become lazy, I just shoot and expose roughly right.
I am thinking of a night time scenario where my ISO might float around 12800 (and up) and I'd like to slow down my shutter to get the ISO down. In these situations a little burst helps make at least one stable shot, and why not make it a 3-frame bracket by ISO.
It is also true that maybe the slow 135/3.5 or a 200/4.5 is not the right nightscape lens but at least Nikon's sensor could technically allow good results. With bursts one could achieve usable shots at 1/60 - 1/100 sec and I just think a bracket could be cool since one doesn't always predict correctly if the exposure is a spot-on or not. Two birds with one stone.
