This further interacts unpleasantly with linux downstream, because obviously MTP mode fucking sucks (root_squash, or whatever the fuck -- it's just a dumb mode for peripheral cards, look it up sometime if you feel like getting enraged) and is the default. Normal USB (unhelpfully called "mass storage") mode is also available via settings, but the camera actually encrypts the underlying partition, because <blockquote>sudo fdisk -l Disk /dev/sdb: 63.9 GB, 63864569856 bytes 255 heads, 63 sectors/track, 7764 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdb1 3 7765 62351360 7 HPFS/NTFS</blockquote> <blockquote>sudo mount -t ntfs /dev/sdb1 /media/sonycam NTFS signature is missing.

Most of what comes out of highres-sensor-cum-sad-lens (e.g. crapple pnoje cam, typical example) is thermal noise.
