>From what I understand it is this code passage in the file
common/camera_control.c that handles the previews. So the situation as I
understand it is that when we connect the camera directly, the gphoto
library is served a preview by the camera. But when we connect the sdcard
gphoto will not have a preview version of the image and the file size of my
raw files is larger than 512000 bytes. But since NEF files actually have a
preview embeded it might be possible to read this without reading the whole
file? But maybe that should be inside gphoto2? Does anyone have any
knowledge about that library?
