'normalizing' slide color?

I'm working on a Powerpoint slide show where the photos were
taken by different people, using different cameras and different types
of film. As I run through the slide show the differences in color
balance from slide to slide become very noticeable and distracting.
Aside from individually altering the color balance on each slide, is
there a utility that can recognize big color balance differences in a
sequence of slides, and bring the colors closer together, a sort of
normalized color balance?

Not from within PowerPoint. You would have to take them into a paint program and
do the work there.

Not in PPT but image editing/viewing/manipulation programs like Photoshop (high
end/expensive), PaintShop Pro (very capable, moderate priced), BreezeBrowser,
QImage (inexpensive, shareware but very good) or IrfanView (free, also very
very good) might help you balance images or batches of images.

Expect to do a bit of manual work though. The computer can look at an image
and see lots of yellow, for example, but it's got no way of knowing whether
that's because it's a picture of a white sheet in too-warm light or a picture
of a yellow sheet with perfectly accurate color.

It needs some human intervention.

You'll probably find that most images fall into one of several problem
categories; programs like QImage let you set up "recipes" to apply to each
category, so you might be able to set up a folder for "Indoors, tungsten light,
too warm", "Outdoors in open shade, too blue" and so on then drop each image
into the appropriate folder and batch-apply correction recipes.

Thanks to both the responders. I figured there was no easy
solution, but there's a lot of software out there I don't know about.
So I'll go about it the old fashioned way....one at a time.
