Stick with reality. What do programmers/users know about TIFF, what does it stand for? Any part of that actually changed?

Compatibility with all existing software.

We've seen that argument before. I've replied before (amongst other replies) that the same goes for tiling in TIFF, it was not compatible with all existing software either. So far, nobody contradicted my reply, so let's stop returning to square one in this part of the discussion.

With a tiled TIFF or different compression schemes, the file is recognized as TIFF and gets a more useful error message ("unsupported compression scheme", "unrecognized storage method", etc.).

BigTIFF does have the disadvantage over all previous changes in that it will get "Not a TIFF file" or "corrupt file" error messages from all previous software.

With all due respect, but, that too has been said before.

Photoshop, like most of today's GUI apps, allows selection of file format when saving a file, followed by an option dialog specific to the file format. Are you inclined to feel good about having users select between ClassicTIFF and BigTIFF in the first step,

Yes, because only 0.01% of TIFF users need BigTIFF.

Perhaps the real disagreement in this thread is about the characterisation of the actual/appropriate/hoped-for user population, and their software of choice.

What about a proper comprehensive survey.


to present a different same clone of the same option dialog depending on that choice?
