Canon Camera Controls command line tool
This tool was created so that I didn't have to keep booting an old version of macOS (10.11) to download images from my Canon EOS 50D camera. I had to use this version as this is the last version which would run the Canon supplied tools which are able to retrieve images etc from my EOS 50D.
Interestingly the latest version of the Canon EOS SDK (version 13.13) on the latest version of macOS (11.1) will talk to my EOS 50D without any special setup (apart from using Rosetta 2 - see below).
These tools are built around a C++ interface which uses the RAII pattern for communicating with the Canon EDSDK.
The Canon EOS Digital SDK (EDSDK) version 13.13.0 is imported into the project as a git submodule. This git submodule is the EOS SDK from Canon (Europe) put into git.
This project also uses Poco for general things such as command line parameter decoding and logging. This project uses conan for dependency management (apart from the Canon EDSDK) and cmake for building.
This project currently only builds for macOS Catalina (10.15) and macOS Big Sur (11.0) for Intel 64bit processors - forced when compiled on Apple Silicon. It does support Apple silicon but has to use Rosetta 2 because the Canon EDSDK currently only supports Intel 64bit applications.
The EDSDK produces an error message (see below) when an application using it starts up. It does not (seem to) stop the applications from working correctly.

This project is has not (yet) been setup to build for Windows.
This code produces command line tools lscamera and cpimage.
lscamera either shows information about Canon EOS cameras connected to the computer, or lists the files stored on a Canon EOS camera along with their dates and sizes.
lscamera without any parameters produces a list of all the (Canon) cameras connected to the computer and their information.
lscamera --help displays version and parameter information
lscamera -c0 -f or lscamera --camera=0 --files displays files for camera 0.
cpimage downloads files from a Canon EOS camera.
cpimage "IMG_73*" will download images starting with IMG_73 and put them in a folder named using the date the picture was taken. eg if the picture was taken on 1st Feb 2019, the folder name will be 2019_02_01.
- Complete unit testing, especially of the C++ interface to the Canon EDSDK.
- Provide a means of converting raw images to other format(s).
- Port to windows.
- Provide downloadable executables (if anyone wants one, please let me know!)
