I've decided I don't want to use the Canon PC software if I can avoid it. Both the camera and Jasc Paintshop Photo Album support WIA, a windows thing to handle scanners and cameras. When the Canon software was installed it made itself the default handler when the camera connected. I found that this could be changed as follows:
- connect camera to computer via USB
- Go to conrol panel/Scanners and Cameras. Open Scanners and Cameras itself by double-clicking on it, don't open the camera.
- right click on the camera in the Scanners and Cameras list and select 'Properties' (Note: the camera will not be listed if it is not connected).
- select the 'Events' tab and configure the 'Camera Connected' event to launch Paintshop Photo Album (or whatever you want to download)
- press ok.
Unfortunately this seems to bypass whatever it is that automatically rotates portrait mode photo's to the correct orientation, when copied to the pc they are on their sides. The Canon Powershot S1 IS does have an orientation sensor and all photo's are displayed the right way up on the viewfinder and when the camera is connected to a TV. I think I'm happy to deal with the chore of rotatng photos than use the Canon software.
I am starting to rely on Paintshop Photo Album to organise my 750M of photos. It handles them easily and it uses real directories on the PC, it does not try to hide nasty technicalities like the file system from me.
