Are there people currently active to define a "64 bit tiff" proposal? Is there a list of proposed alternatives?

The other issue that arises is whether we should actively try to get Adobe to lead a new TIFF specification or just produce something ourselves as a community. While it would be nice to have Adobe's involvement, I am not keen on waiting for them.

We want to work on it. And we've been thinking about it. But the interested parties haven't had time to work out all the details.

One thing I would really like is some indication of what other TIFF implementations exist out there beyond libtiff, and if their developers would be interested in working cooperatively on a 64 bit TIFF standard.

You mean like Photoshop? Yes, I'm interested.

By the way, I would forsee a 64 bit TIFF specification (which I imagine we would have to call something different - perhaps BTIFF - Big Tagged Image File Format) being developed essentially only defining low level structural details, with all higher level concepts (tag lists, values and so on) defined by reference to the TIFF 6 specification.

Actually, there are lots of things that could be cleaned up if we had a new specification.
