Some notes around the Sony RX-100 I use.

• connected via usb cable the camara can be accessed from Linux using the usb-storage driver
• ImageMagick can not directly read the raw pictures, dcraw should be used: yum -y instal dcraw
• https://www.imagemagick.org/Usage/formats/ has excellent informations regarding file formats
• this is the workflow I use to rework pictures for web album: photo_workflow
