I know I've come to the right place but I should warn you, this might be
a really stupid question. Technically savvy, I'm not.
I'm using a D30 with the 550EX, and I'm having a terrible time with
ETTL. For years, I used a 1N with the 540EZ, had no problem at all. I
knew that flash's capability fairly well and could get exactly the right
amount of light out of it.
I rely on TTL. I do a lot of very fast, candid shooting, and I prefer to
have the kind of light on my subject that keeps them from looking
"flashed", so I constantly balance my flash output with the available
light, and actually only use flash when I really really have to. But
with the 550EX on the D30 it doesn't seem to matter how I've fixed my
exposure, the flash (either as the main source of light or as fill) on
ETTL is wildly inconsistent. I can shoot two, three, four frames in a
row of exactly the same thing on exactly the same exposure setting with
the same focus point and each time the flash will give me a different
output (I normally use a Quantum 1+ to power the flash, but I've tried
using AA batteries just to make sure it wasn't the battery pack that was
at fault - if that were even possible). If I'm ten feet or so from my
subject, in bright sunlight I can't get any fill on them at all, even if
I crank up the flash's output - if I move six inches closer and crank
it back down, wham! - completely overexposed.
In marginally low-light situations, even if I meter for ambient,
overexposure - and I mean extreme overexposure - seems to be the norm.
So the flash is working, it's just not giving me the amount of light I
want when I want it.
I haven't seen any questions like this on the list, so I'm afraid there
must be something quite obvious that I'm completely overlooking, and all
you D30/550EX users out there are reading this and rolling your eyes and
thinking I'm a complete idiot.
So, any advice anyone?
