5 discs to save 130 photos???? I recently asked advice on converting files to .TIFF after putting them on your computer. So, now I am ready to save my pictures and holy cow...now it takes huge space to save on a disc as opposed to the JPEG...Can anyone tell me how they get around this? thanks a bunch!

you can fit more on dvd's

So you would put on a DVD and not compress the .TIFFs or change to JPEG?

Yeah, DVDs can hold A LOT more. They cost a bit more than CD-R's or RW's. Plus you have do have a DVD burner and not just a CD burner, right? Yeah, TIFF images are better than JPEG I believe.

5 cd's don't take up much room. you have 8 bit vs. 16 bit Tiffs to choose from.

Lisa, TIFF files are lossless files. This means that you can open and close them and work on the images and you will not lose any data. This is not so with JPEG. Each time you open a JPEG file and work on the image and close it you lose data. I have attached some additional information concerning TIFF Files. I hope this inforation will help you. Keep shooting. Doug The Tagged Image File Format (TIFF) was designed from the ground up to alleviate the problems associated with fixed file formats. The key word here is designed. TIFF did not evolve from a de-facto standard. It was created to become the industry standard for image-file exchange. TIFF was a super-set of all existing graphics or image file formats. TIFF incorporates enough flexibility to eliminate the need or justification for proprietary image file formats. As a matter of fact, it is possible to store proprietary information in a TIFF file without violating the intent of the format. TIFF was designed with an eye toward the future, not just for use in the present. The designers of the TIFF file format had three important goals in mind:
a. Extendibility. This is the ability to add new image types without invalidating older types and to add new informational fields to the format without impacting the ability of older applications to read the image files.
b. Portability. TIFF was designed to be independent of the hardware platform and the operating system on which it executes. TIFF makes very few demands upon its operating environment. TIFF should (and does) perform equally well in both the "IBM PC" and Apple Macintosh's environments -- and UNIX.
c. Revisability. TIFF was designed not only to be an efficient medium for exchanging image information but also to be usable as a native internal data format for image editing applications.
The correctness and the accomplishment of these goals is somewhat corroborated by the number of software vendors supporting the TIFF format. Every major scanner manufacturer and every desktop publishing program supports TIFF. More application programs support TIFF every day. Also, numerous translator programs that translate other image-file formats to TIFF format are becoming available. (We have GWS and Sunshow, among others, legally available for EE 458).
The richness of the TIFF format solves many problems, but at the same time creates a few all its own. The TIFF file structure is necessarily complex or (a better word) variable. It's more complex, in fact, than many of the proprietary file formats it was designed to replace. The added complexity of the TIFF format requires much more code to manage it than do most other image-file formats. This results in slower execution times reading and writing files and in longer TIFF code development cycles. However, since we intend to concentrate on image processing -- we're not interested in re-inventing a graphics file viewer -- we can make certain simplifying assumptions which make most of the tougher problems quietly go away! I'll go into those simplifying assumptions shortly.
We shall support uncompressed TIFF revision 5.0, which is what Deskscan produces. (Deskscan is the driving software that we have for the HP scanners in the microprocessor lab). The TIFF format is controlled by a specification jointly written by the Aldus Corporation and Microsoft, although many other companies, in addition to these two, contributed to its formulation. Version 5.0 of this specification is dated April 1988. Although the specification document itself is copyrighted by the Aldus Corporation, the TIFF format is in the public domain. This means no fees or royalties are required to use the format.
The specification document is available if you want it; unlike most other specifications, it is quite readable. The discussion to follow only highlights TIFF functionality. Any other questions you might have about TIFF will be answered somewhere in the spec.
Finally, a few good articles have been written about the TIFF file format. You should be able to locate a source of information from a reasonable library if necessary.

I think he's saying "yaaaay tiff files!!"
