In Thom Hogan's book (CD) one of the tips he gives is to make sure when you
put your camera away you change any settings back to normal.  Well, I had
just taken some macro photos using an incandescent lamp, had changed the wb,
and put it away like that.  Later that day I grabbed the camera to shoot a
cat that someone brought over (very cool looking cat, exotic, expensive
hybrid) and used the flash.

Anybody want some pictures of a blue cat?  It's exotic, but it ain't blue.
And because I didn't shoot the images in RAW it wasn't easy adjusting the
colors back.  I used Nikon Capture and used the red blue and green
sliders -- got very close.  Anybody have an easier way to fix something like
this?

At least I did get some good shots after I set the wb back to automatic.

I did something very similar myself when I first went digital. I shot a
bunch of portraits in a room that had flourescent overheads that couldn't be
turned off for some stupid reason or other. As I was using studio strobes
anyway I set a custom WB using a sheet of white paper shot under the
strobes. Everything went fine with the portraits printing out the right
colour.

The next day I went to an airshow. Got lots of shots of very pretty military
jets whizzing around....all with a distinctly green cast.

Oh God, a lot of us have done the same thing, of course NEVER more
than once, right?!? <grin>.   Oh and I've never done it myself of
course (cough cough, wink, nudge).

Thank God and Adobe for photoshop!

It's a common error, and digital cameras are much worse that film as
there are so many additional setting related to the capture.  You can in
many instances correct for it.

Try pulling the blues and increasing the red/yellow.

I don't like trusting the auto-WB.  I prefer setting the light
temperature and that works for the three main cases, sunlight/flash
(5500K), incandecent (2800K) and open shade (I haven't found the temp
yet, but my camera goes up to 9900K so I'll start there.  It's -12C
outside, so I'm no rush to do this...)

Cheers,
Alan

I find that using Curves in Photoshop CS is a quick way of correcting a lot
of mistakes like this. Doesn't always work, but it is worth a try. Using
Options in the Curves of Layer box and clicking the white or black squares
to set their values to extreme white and black can be very helpful.
Sheldon - 09 Mar 2005 16:47 GMT
Thanks for the suggestions, and letting me know I'm not the only one out
there who does this.  I guess that's what the tips in the book are for. :-)
And I just finished reading the book!

At least you had something reasonably correctable! I did the same thing
with the ISO on my istDS. I took a picture or two at 3200 just to see.
The next day, snapped lots of photos of my niece from Texas. Couldn't
figure out why they were so noisy until I looked at the Exif info.

There's a fine line between stupid and clever.

My frequent mistake doesn't ruin the pictures, but it makes you look like an
idiot!  When I do macro or still life type shots, with a tripod, I set the
camera to timer mode because this is what the infra red remote control needs
it to be on.  You feel like an idiot next day when you press the shutter and
then have to stand there for 10 seconds before the shutter releases.

Be glad you don't have to keep resetting this after every shot!

Hahaha, I do both the 10 sec timer and WB things.  I've been faithfully
setting things back to normal and AWB lately, though.

I have a different approach.  I Always assume I left the camera in a bad
state, and that all settings are suspect every time I turn it on.  It
doesn't take long to check them.

Now I now what the ammo fairy does to relax -- puts bad settings on
cameras.

:-)

(The ammo fairy, my gun-toting friends tell me, is the entity who
loads your unloaded gun when you put it down for even a second.)

    Sometimes it only makes sense to focus our attention on those
    questions that are equal parts trivial and intriguing.

Me too.  (But a _little_ more discipline would help.)

The problem, although it's rare for me, is for people who grab events as
they occur.  It is best to always have your camera in a known state when
you grab it from the bag.

One thing I sometimes do is leave the mirror lockup mode engaged, which
on a Maxxum means you press the shutter and the mirror lifts and then
there's a 2 sec. delay before the shutter releases... so, you develop
the habit of just holding still when this occurs and get the shots
anyway (as long as there's no action involved).

Cheers,
Alan.
