Yes. I’m used to large files, though. When I scan film from the 67 using my Nikon 9000, I end up with about 90 megapixels. Those tiffs are over half a gig each. The difference is that I always have the film, so I scan only what I want to show.
And 4x5 film even in my Epson 750 creates 90 megapixels.
But with the Pentax, I’m dealing with storing all the photos as raw files.
I didn’t realize this early on, but I need to be able to apply nondestructive edits on top of a raw file, and keep that as the storage medium, rather than processing them all into tiffs (which are 4 or 5 times larger), and then editing. So, the raw processor needs to be the principle editor for most targets, and the source for lower resolution files targeted for screen display, with something like Photoshop being reserved for the few special cases.
That’s a change in basic workflow made necessary by having 645z files in the thousands from just one trip. I had processed an initial edit of a little over 800 images, and at 300mb each in tiff format, it’s not sustainable. I’m feeling my way along with files this size in a production environment.
With my Canon, I could frequently use the jpgs for production applications, but even as PSD files, they are much smaller. The Pentax files invite too much adjustment for the jpgs to serve that role.
