"The TIFF format has been seriously degraded.Adobe owns it, so they can do whatever they like with it, which is unfortunate because so many of us depend on its stability to make a living. Some years ago, the spec was amended to permit, among other things, layered TIFFs or those saved with JPEG or ZIP compression....
What happened is that Adobe added some *options* to the TIFF format. If you try to use the optional compression, it even gives you a warning in a pop-up. If you want "traditional" TIFF format, you save with no compression.
This seems to be much ado about nothing.
