Although the TIFF format supports multiple pages there aren't many applications out there supporting the multi-page flavor. Adobe Photoshop doesn't, I believe (I haven't tested with CS3 or newer) -- even though the TIFF spec is published by Adobe. The likely reason is that multiple-page TIFF has a completely different purpose than TIFF for graphic arts production.
Unfortunately I don't have a multiple-page TIFF handy, but I'm quite certain that Adobe Photoshop can OPEN such a beast, but upon SAVE operations I suspect it will effectively remove anything but page 1. I'm unaware that Adobe should have changed this behavior since I tried some time back. Hence, be careful with the choice of editor for such TIFF files. Back-up and test carefully !!! The only tool I know of that actually can write multiple-page TIFF is Ghostscript's tiffgXXX devices, which typically uses G3 or G4 encoding. G3 and G4 is primarily targetted against transmitting/storing Fax messages, i.e is not too relevant for Photoshop to deal with -- perhaps except for compressing 1-bit lineart. I'd say it's generally risky business to use this TIFF flavor in a graphic environment.
