Filenames on DP2M card
I have a variety of filenames appearing on the SD card I use in my DP2M camera: they begin with SDIM, DP2M, and _P2M. I know this has to do with the color space selected in my shooting menu, but there are only two settings, SRGB and Adobe RGB. So how is it that there are three varieties of filename?
The manual mentions only two alternatives: SDIMxxxx or _SDIxxx!
