I'm not too familiar with the DNG format, but if a DNG file could be as simple as [header][2304x1296x2 bytes][footer] then it might be possible with the current hardware.

But without a filesystem, would it be useful to have DNG files stored on the SD card? Wouldn't you need special software to read off the "packed" DNG data anyway? And if you need special software anyway, couldn't the special software convert the existing raw image data to the DNG format, instead of requiring the hardware to do it?




Well, yes.

It's unclear from the website what Photon Transfer does exactly, but from the screenshots it seems it's almost a Lightroom-lite?

A super basic utility that would simply extract the data from the device and spit out DNG files, with zero further processin, would not need to have a nice GUI, or even a GUI at all, and may be enough to lure in Windows users?


The DNG/TIFF spec is unreasonably flexible. It would be possible to add just a fixed precalculated header on the image data to make it valid DNG. The lack of filesystem is still a bigger issue.


Your header for your DNGs, I think, is going to be the same for every single file you write. DNG is just a kinda superset of TIFF, IIRC.
