Program for color correction (fixing white balance)

Is there some freeware program that does this (by clicking on a gray
or white part of the image)?

No freeware that I'm aware of, but MS Picture It does
have that function (for a price)

And Photoshop, and Photoshop Elements.

It is not free, $39.95, but I consider it priceless.

Go to prodcuts>color correction tools> white point

This PS plug lets you click on the part of the image that should be
white and does in a couple of seconds what could take minutes or more
using Pshop's various color correction tools

I use it every day. If time is money, then this plug-in is more than
free. Note: I am not affiliated with the Imaginf factory, just an
ardent user of its products becasue they work.

Oh yes, you have control over how much to apply the filter as well as
whether to have it also adjust the white point to 255 or +/- 10% which
means you seldom have to go back to adjust levels or curves
before/after applying the filter.

As a side note, they also make an excellant perspective correction
plug which I use all the time when using my wide angle lens shooting
architectural pics. Makes lines straight like a view camera, without
deterioting the image (though it does alter the frame and you have to
crop away the excess background)

my 2 cents, Robert Storm

FYI .. Paintshop pro has a similar tool in the color balance
adjustment .. "remove color cast" and it works very well especially
with blue casts due to improper WB settings/measurements ...
FWIW
