I am digitizing positives (slides) for an architectural heritage firm. The executive director had been, for many years, using these slides on a slide projector. I am a library student who is cataloging these images and scanning them for archival purposes.

When I convert the slides from archival quality tiff files to PowerPoint efficient jpegs, there seems to be no quality loss. My boss takes the slides, inserts them into his PowerPoint presentation (goodbye slide projector, hello 21st century!) and WHAM! Loss of quality. He is running PP 2010.

When I insert them on my laptop, PP 2007, the images look fine. Even when I take his PP presentation and plug it into my computer, I can "Change" the pictures (using the "change image" function when you right click on an image) to the EXACT SAME picture file and like magic, the quality is perfect.

He has tried inserting the images into a word doc on his computer and the images look fine. SO, we've deduced that the issue is PP 2010. Any thoughts?? He would really like to make the presentations on his desktop and not my jalopy of a laptop!

Thanks!
