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.
