How to copy photos from USB PTP camera?

If the camera is connecting to computer by USB and has set as a USB device, then we can copy those photos by gphoto2 and gphotofs.

You might need to unmount from a file manager if automounted as we need to Make sure no other program (gvfs-gphoto2-volume-monitor) or kernel module (su ch as sdc2xx, stv680, spca50x) is using the device and you have read/write access to the device.

#sudo apt  install gphoto2 gphotofs

Look around

#gphoto2 --summary
#gphoto2 --auto-detect
#gphoto2 --list-ports
#gphoto2 --list-cameras
#gphoto2 --list-folders
#gphoto2 --abilities

There is 1 folder in folder '/'.
 - store_10000001
There is 1 folder in folder '/store_10000001'.
 - DCIM
There is 1 folder in folder '/store_10000001/DCIM'.
 - 129_FUJI
There are 0 folders in folder '/store_10000001/DCIM/129_FUJI'.

Make a directory for mounting USB PTP camera

#mkdir /home/kusanagi/usbptp/

Mount USB PTP to the directory

#gphotofs /home/kusanagi/usbptp/

Copy photos which was created today to current directory

#find ~/usbptp/store_10000001/DCIM/129_FUJI/ -daystart -mtime 0 -exec sh -c "cp {} ." \;

Rename photos with exiftool

Today is 20230402.

#sudo apt install libimage-exiftool-perl

#mkdir /media/kusanagi/toshiba-pc-l200-1/20230402{,-smallres}/

#exiftool '-FileName<${CreateDate}_${Exif:Model}_${filename}' -d %Y%m%d_%H%M%S -v1 *

Generate smaller resolution photos for sharing / backup

#find . -iname "*jpg" -exec sh -c  "mogrify -path /media/kusanagi/toshiba-pc-l200-1/20230402-smallres/ -quality 95  -resize 1440x1440  {} " \;

#find . -iname "*jpg" -exec sh -c  "mogrify -path /media/kusanagi/toshiba-pc-l200-1/20230402-smallres/ -quality 95  -resize 1440x1440  {} " \;

Done, unmount gphotofs

fusermount -u /home/bob/usbptp
