WHAT FORMAT

GRAPHICS GURUs OF THE WORLD.

I need a little help.

My son is going to prepare a Power Point presentation for our 50th wedding A.

I am to furnish him scanned photos, some color, many B&W on a CD.

MY question is what format should I save the scanned images in.

He will NOT be trying to enhance the photos other than size and maybe some captions.

Thanks much in advance.

jpg (also jpeg & jpe) are the way to go... relatively small file size, just about every software package supports them.

PowerPoint can handle just about anything... definitely jpgs

Ditto. Bitmap will be too large and slow to down load. Other formats, like for Adobe's software, may not be supported.

JPG images can degrade with copying. Set compression at the minimum.

TIFF and BMP files are larger, but load quicker because they are not compressed. They tend to not degrade with copying. Most high resolution cameras prefer those formats.

GIF has some spotting support, and are medium between JPG in compression and uncompressed files.

Power Point or Corel Presentations will accept all of them. WORD munches most file types, but WORDPERFECT has a problem with newer .jpg files.

Terrell's statement that JPG's degrade with copying is a little misleading.

If you "Open" a JPG, then "Save as.." a JPG, you'll get the kind of degradation he's talking about. If you simply copy the file through the operating system, as in transferring a file to a CD, no degradation will occur. JPEG (Joint Photographic Expert's Group) is a lossy format. The more compression, the greater the loss. If you choose that "Save As..." to save something already compressed, it will compress the picture more, and cause further losses.

BMP (Bit-Map) is not so good. They're big, and have color problems on some systems.

TIFF (Tag Image File Format) preserves all the picture information. It is not compressed.

JPEG2000 and PNG are the two newest formats. Older software will not read these, so although they are "better" compressed formats, you should avoid them for another year or so.

What I do with family pictures is to scan and save in TIFF. Files are HUGE. CD's are cheap. When someone wants an album, I use JPG with medium to low compression, depending on whether the recipient will view the pictures on screen or will print them out.
