I can't think of a reason why moving a table to avoid a shadow would have
any effect on your ability to pre-set your white balance.

You mentioned this problem sometime happens with the camera set to "A" or
"M". I've never used a D40, but if I had to take a wild guess I'd say when
you are in "A" (presumed to be Automatic) you are automatic (point & shoot)
all the way and therefore limited to auto white balance. But in "M"
(presumed to be Manual) you are able to manually pre-set a custom white
balance.

With Nikons "A" means aperture priority. If you want to use program mode
put the camera into "P" mode. However, neither mode should affect the white
balance adjustment.

You know, Rita, you take a lot of flack here and in the other groups
where I see your posts. Undeserved, I think. I can't see why other
people don't understand you're just having fun. We're all in
newsgroups to suit our own needs, and your need is have a few laughs,
posts a few pictures (good ones, I think), and to tweak the noses of
those who need a pokerectomy. Or is it "pokerotomy" when the poker
needs to be removed? (Checked: it's -ectomy.)

Yeah, you're right. I had the f-stop too open for the light. For the
other posters..."M" is manual aperture and shutter on the D40, "A" is
aperture priority, and I'll shoot RAW when I'm damned good and ready.

On the D40, you put down the card so the card fills the view and push
the shutter release. No focus is necessary and no image is taken.

I do wish you'd stop writing "LOL", though. Anyone you have to tell
that you're laughing isn't going to understand anyway.

IRC 18% grey was used to calibrate and check meters, not color. Those of us
who couldn't afford a grey card used grass or the back of one's hand.

A Shirley card was used to make color adjustments in the darkroom.

However, in the digital age we started to use lenna as the standard. (Kodak
was too stodgy)

the story of lenna. For those with real curiosity, lenna was a Playboy
centerfold model, circa 1978.
the full story is at:

I apologize to anyone offended by this minor, but on point, diversion.
