WB SHIFT/BKT: This allows you change (shift) the white balance slightly, or

bracket them (make several shots, each slightly different).

Shift: This is what you do to make subtle color shifts to images. To do

this, press MENU, spin the dial to select WB SHIFT/BKT, press SET to

get into it, use the unmarked rear navigation button to set the color

shift, and press SET to lock it in. Oddly the center push of the button

won't get you back to 0; you have to click back over the hard way. (The

30D ignores you if you forget to press SET.) This shift is subtle, you

have to look carefully to see it. If you set it away from 0, you'll see a

small "WB =/-" on the top LCD to remind you.

Bracket: Spin the big dial and you'll see three dots where before there

was just one. Spin in one direction to get red/blue bracketing, and in

the other direction for green/magenta. Shooting this way is easier than

exposure bracketing, since the 30D automatically records three files,

one for each exact WB, for each shot. This is because WB is

calculated internally for each shot, unlike exposure. WB BKT records

three frames from each shot automatically. Of course you also always

need to press SET for these settings to take effect. You may shift the

WB as in the above paragraph, and then bracket around it. Slick!

The unslick part is that this WB offset takes effect for all other WB settings. To

turn it off or on or change it you have to get into these menus. You can't save

a different value for Daylight and another for Cloudy, as you can on Nikon.

Nikons are better because they make changing this as simple as spinning the

front dial while holding the WB button. Nikons are better because they store

and recall the WB trim (shift) separately for each WB preset.

Canons are better because they also allow altering the WB along the

green/magenta axis, which Nikons don't. Personally I never use

green/magenta bias anyway. Canon also provides more adjustment points,

although I find Nikon's +/- 3 settings more than enough. I prefer the Nikons

here.

CUSTOM WB is how you set the 30D's white balance to a white or gray card

or Expodisc. It's complicated, unlike Canon's compact cameras.

To set the WB to a random reference, first make a shot of the entire frame

filled by that reference, but do it in anything other than the Custom WB mode.

The Custom WB mode is an icon of a little square in the middle of two ramps.

Now press MENU, spin the big dial to CUSTOM WB, press SET (spin the dial

again if you want to set the WB to an image other than the one you've just

taken), press SET again to set the WB to that shot. You'll probably get a

reminder now to set the WB (use the WB button) to Custom (square and two

ramps).

If you did this correctly, your next shots will have perfect color balance.
