In fact, in version 7.0, it saves by default in the format the file was
in when it was first opened, unless incompatible with the new content.
The only file format output that imbeds profiles on my scanner is 8 bit
TIFF. PS6 used to propose PSD once the file was modified to include
layers for, PS6 could not save TIFF layered images unless flattening
them first. Now in PS 7 the default for TIFF is TIFF with layers. I have
been told off list that the upgrade 7.0.1 helps in resolving those
choices. So when the french version is released, it might help. But that
isn't a big issue.

That was the concern. The lean PSD format proposed in PS 7 is very
useful to save large files. When you start with a raw scan of more than
two hundred megs, there is a huge weight difference between it and the
weight of an image that includes a flattened image. In PS 6.1, saving a
200 megs image with a curve layer doubled it's weight. Now in PS7, in
TIFF layers mode or in PSD mode with compatibility on you end up with a
400 megs file too. But in the lean format with compatibility off, the
file remains the size it was when you opened it and that's a great time
and space saver! I always keep an older version of Photoshop on my disk
so it should always be possible to open the file and re-save as a
composite image if needed. The point is to know that you should do so,
and I think Adobe will probably include a message saying that "this file
was created with an older version of Photoshop..."

I didn't know it was there. Had I known, I would have probably used it.
Or you probably mean that the fat format was there. I also think that
TIFF was only for flattened images before, although strangely PS 6 can
open a TIFF multilayer file.
Bottom line, I think we should be very happy with the new "incompatible"
format. By the way, what names does Adobe give to what I call the lean
and the fat format?
