I'm working on a project which I need to take images automatically from a DSLR camera and should save it in the raspberry pi's SD card. There was a tutorial it shows how to save the image into sd card on DSLR camera but that's not what I need because I need to get images saved on the raspberry pi's SD card for future image processing works. So I should save the picture inside raspberry Pi's SD card. Please show me a tutorial or a guidance to get this done. I'm a complete beginner to this raspberry pi implementations.I'm using py charm IDE for image processing and Python 2.7
