Shangarah, this calls for more exchange of info between agencies and photographers indeed, and maybe, there can be some business here for those developing software for better lossless jpeg compression ( if that can exist). I remember there is this ProJpeg Shareware and they claim their compression in jpeg to be optimised as compared to that of PS. Should that or any other alternative really fills the gap in the storage dilemma, I tell you it means lots of space saving for both photographers and Agencies, since it is one of those Digital Urban Myths that no serious photographer will ever keeep or deliver his/her work in Jpeg and only Uncompressesd Tiff ( not even using the lossless LZW compression) should be applied. Also, I have received lots of files saved as EPS with jpeg compression. They are small files and many claim it is practically lossless, Perhaps it is time to set up the same tests with this format. I can't remember the reason for me not to use it often , other than tiff is tiff and nothing beats tiff. THis would be a real myth breaker!! The only option I had found so far with storage in CD's is that of compressing the folder of uncompressed tiff files with Stuffit DeLuxe, achieving almost double the space available, this is, doubling the number of files to save in a CD, but still this only allows for some twenty something fles of 50-55 Mb, and I promise you can go and have a long cofee break while waiting for the decompresion of such 700Mb compressed folder , and still you may be facing problems of Mac to PC compatibility with Stuffit Archives...
