colour cast on photographs in Word

Operating System: Mac OS X 10.5 (Leopard)
Processor: Power PC

A Word file is made on a PC by someone else and emailed to me. It contains photographs.The photographs are JPEGs, often ones I have taken myself and sent to the person who assembles the document.
When I open it on a Mac, one or more of the photographs has a colour cast, green or magenta, that I can't get rid of without re-inserting the photograph on the Mac. Does anyone know why?

No. My first thought would be that the other end has applied a colour
correction.

Noting that the Gamma is 1.8 on a Mac and 2.2 on a PC, and the colour
temperature is 6,500 compared with 5,800. if they have corrected to what
they are seeing, it should come back to you looking a bit redder than it
left.

But if they don't know enough to colour-calibrate their monitors, then
chances are all they did was "fiddle" with the picture in Word.

Try temporarily adjusting your Gamma to 2.2 and your colour temperature to
6,500 so you see what they might be seeing. You will notice a shift much as
you describe.

Cheers

Thanks for your reply. I don't think the people setting up the documents know anything about adjusting photos in Word. I tried your suggestion, and it made me look harder at the colour effect. Here's a better description:
Open a photograph in Photoshop. Make a Curves layer, and add points to the line as follows:
In 128 Out 187 : In 155 Out 199: In 177 Out 193: In 234 Out 201. This (abnormal) curve gives some idea of what happens to the photograph in Word. Add to that a colour cast/shift that I can't reproduce, and you have an idea. It looks similar to a print from negative that's been been badly processed and has crossed curves.

Well, yours is the first report I have seen of a colour SHIFT in Word for
Mac. If this were Mac Word's doing, I would have expected to have seen
hundreds of reports: you know how graphic-aware the Mac user base is!

If you care to zip up some samples and email them to me, I'll send them in
to Microsoft for you and see if they can figure out what happened.
