For a lot of poeple now using stiching software, doing large format printing, or digital muraling, we're limited by a 4gb tiff limit. This means for prints bigger than around 15ft x 9 ft we need to start chopping ppi to export as a tiff. As someone who works with tech often printing 40ft murals, it would be so helpful to be able to save as Big Tiff files instead of just Tiff. I know this is felt by many people in the gigapixel and large print world.

And you increase the chance of your RIP choking with huge files. A 40 foot mural could be maybe 15-20ppi, 8-bit, and look fine.

Just so it's said, because it's a very widespread misunderstanding: you don't need 300 ppi at those sizes; it's just wasted.

Even the best pair of 20/20 eyes cannot possibly resolve 300 ppi at more than 25-30 cm distance, in other words as close as it's normally possible to get. That's close newspaper-reading distance (if you remember newspapers 😉 )

As a general rule of thumb, anything above 20 000 - 25 000 pixels is most likely wasted. That's enough resolution for anything. Billboards and wallpapers can be 10-15 ppi and look razor sharp because it's seen from farther away.
