Ah, thanks for the query, GianLuca. Just tried it again. I can load the
DNG but cannot load a PEF. But a pixel-shifted DNG will only load the
first of the embedded four images. This is normal for a new camera model
- DNGs will usually load in dt but proprietary raw formats need some
tweaking to dt by devs before they can be read.
