Mac Forum / Applications / PowerPoint / November 2005Projected Images Not Sharp
I finally bit the bullet and had my old 35mm slides digitized. After laboring intensively, I put together several ppt presentations, using powerpoint X. Now I project the presentations on a classroom screen and they are not sharp (especially the photographs). The slides were converted to jpegs, mostly in the range of 860x500. I hate to ask this question, but will I need to have hundreds of slides re-digitized to a higher resolution? (please tell me no). > I finally bit the bullet and had my old 35mm slides digitized.

(please tell me no). I could tell you no but <NixonMask>it would be wrong</NixonMask> Your projector and computer are probably set to 1024x768 or better, so the images aren't really high rez enough to match even that relatively low resolution. Also, JPG is a reasonable format to use for inserting photos into PPT but it's not the best "archival" format. Better practice is to have the slides scanned at substantially higher resolution, say 2048x1366 pixels or even double that and saved as TIFF or PNG (both of which use lossless compression). Keep those images intact, never edit them. Instead, make copies and downsample them to a resolution and file format that's appropriate for your intended use. In this case, try saving to JPGs at 1024x768 pixels or just a little higher resolution. Also, make sure your projector and computer are set to the same rez. Most modern projectors will resample on the fly if the computer sends them something they're not set for, but the results are not always pretty. ================================================ Steve Rindsberg, PPT MVP PPT FAQ: www.pptfaq.com PPTools: www.pptools.com ================================================ Steve, thanks for the recommendations. The images are nice and sharp on my 15" Powerbook screen, but when projected...Yuck! I just bought myself an early Xmas present, a Sharp XR-10X projector. The images are much better on it. Rob |
