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!

Do you see the quality loss in show mode or in edit?

If in edit is it only AFTER a save?

Hi John. Loss of quality can be seen before the save. It happens when in edit mode and in show.

My boss has a large computer monitor with a higher resolution, which I thought, at first was *the* issue. But, when that same slideshow is shown on a "regular" resolution screen (so, 1260 x 800 or some such resolution) they are still blurry. Any slideshow, with my slides, that are made on his desktop, appear in poor quality. He can insert digital camera photos that do not get blurry.

He actually shows the presentations on a laptop, which has the resolution that the images were made for (output in the scanning process).

So, this would account for the blurriness on HIS large screen, but not once the presentation is shown on a regular sized monitor.

I would check the resolution setting in PowerPoint SLIDE SHOW Tab >> Resolution is not not set low and maybe that in File Options Advanced 'Do not compress images is ticked' (usually only affects after saving though) Otherwise - don't know!
