I have made a G-Drive link for anyone to analyze. And did DNG file size tests (info below) but have not analyzed the data. Not quite sure what I would look for beyond the obvious.
It includes the raw files, lossy compressed and uncompressed DNGs made from ACR within Bridge (newest update), low res lab scan reference, and jpegs made from my raws. I also included a quick readme with some extra info and the very basic linear color profile I made using DNG Profile Editor. I am open to suggestions on how I might do any step in this whole process better.

If anyone wants to add their single capture/pixel shift capture files to the pile, let me know and I will send you a private link to do so. I think some color neg and slide films would be great to peek at, especially from various brands. No need for DNGs at the moment.

FILE SIZES - For my example image used in this thread the sizes are as follows for
Single capture
- RAW - standard capture - 66mb (not shared, likely uses slight compression)
- RAW - single image from within PShift - 85mb
- DNG - lossy compressed - 13mb
- DNG - uncompressed - 65mb
8x Pixel Shift
- RAW - in-camera - 339mb
- DNG - lossy compressed - 35mb
- DNG - uncompressed - 242mb
As long as the uncompressed data is not modified somehow, thats a nearly 30% file size decrease. If the lossy compressed ends up being fine… I would be surprised but happy haha
Cheers y’all
