Colors corrupted in PPT

[Brenda from Michigan]

User has PowerPoint 2002 SP3

He uses a Nikon D200 camera with flash and a memory chip to take photos of
industrial sites. True color representation is critical. He saves his
photos from the camera to a network drive, then inserts them into PP.

After inserting fine into the initial presentation, the colors are skewed
when the file is reopened. There are blues, greens, reds, purples, yellows
and other colors that appear on the slide that were not there in the picture.
I discovered that if we used file handles to enlarge or reduce the size of
the photo on the slide, the colors would change, sometimes when you got it
just right it went back to the original picture's colors. Changing the Zoom
setting also changed the colors. I tried importing these photos into a Word
document and got the same results.

Can anyone give me a hint about what might be causing this strange behavior?

- What format are the photos from the camera (.jpg, .crw, .tiff)?
- What color space are photos (RGB or CMYK)?
- What is the file size of image?

Both of these can have an impact on PowerPoint's ability to successfully use
photo. You can either adjust settings on camera, or open images in an image
editor and convert to PowerPoint friendly format (RGB, .jpg, less than 1MB
each).

They are in JPEG format. I don't know the size or the format. I don't know
what a color space is either, sorry.

A space color is the possibility thr possibiity to show colors. Each hard
has his space color. Yoou can see it in Photoshop (I think you have to go in
the Picture menu. You can also search on the web: L*a*b ; Adobe 98 ; sRGB
for example. I'm sure that wikipedia will help you
Have you tried on an other computer?

2,000-2,500 KB, the Sony camera (no Power Point issues) jpeg are 1,700-2, 400
KB.

I think you may want to ask the creator to look at his color profile in
Photoshop.

This is not the same problem, but it describes the fix well:

Transparent areas of graphics turn black
