We are using scanned and digital photograph images for catalog purposes and also for reproduction of old photographs. In this last case, we often receive (temporarely lent) family photographs wich we have to return to the owners a few days later after beeing copyed. Dificultly we will have the chance of having it again, so that's why it is important to have the best possible copy. For using in ecran or web of course we can convert in GIF or JPG, but we allways must have a "master" image for publishing for example. The fact is that I got "shocked" with the size of the file (about 90 M) in TIFF wich is apparently the best option for the "master" image. Even with CD-R possibilities that's too much... Anyway your comments have been extremely interesting. Thank you. Emanuel
