Okay. So I make my exposure with no
light. Then, automatically, the camera
makes another. The second would be the
same, since the first was taken with
absolutely no light; one is subtracted
from the other -- leaving what? The 80
second exposure -- by the way -- was the
only one showing a noisy background that
might have been a nuisance; the others
were remarkably good. Maybe 80 seconds
is too much for the noise reduction routine?
This experiment was not done for me. I
will never use 1600 for serious things
and the exposures will always be less
than a second or two. A friend in
Oklahoma is planning to buy his son a
digital camera for Christmas and asked
me to do this test.
By the way, the new camera has not yet
arrived. The agents are waiting for a
shipment and will send it next week. I
am to send this one back in the same
box. The six volt battery has been
running the camera since I mentioned it
had arrived and reads 5.8 volts. The La
Crosse charger, which arrived yesterday,
is trying to bring back a set of NiCads
to life that may be beyond resurrection.
They were almost new (unused) but a few
years old.

The camera's noise reduction software is telling it to make multiple exposures.
It takes quite a while to complete that process.

Hi all,
Today I did an experiment to check noise
at ISO 1600. I capped the lens, put the
camera in a black bag and made a series
of exposures 20, 40, 60 and 80 seconds.
But this is the interesting bit:
After the first exposure the shutter
wouldn't trip a second time. I took the
camera out of the bag and saw the egg
timer was displayed. It was almost a
minute before it disappeared and the
camera was back to normal. This happened
after every long time exposure. Does
anyone know why this should be? Why
should the buffer unloading itself to
the card, or whatever it is that is
happening, take so long to complete?
