By this means, the fastest shooting speed is obtained (although high-speed cards are recommended).
SDM will also save a pair of image-strips of defined width, equally spaced about the image centre and normally with the camera vertically orientated.
This allows the creation of very large stereo, 360 degree panoramas of static subjects using a single camera rotating in front of a central point.
Further details are to be found here.
SDM also works as a slit camera, building a composite image of almost any size in-camera.
The 'slit' covers the entire horizontal width of the camera and may be just one pixel wide.
This feature can be used for recording the periphery of objects
or for creative 'streak' photography :

A folder containing a mixture of these three types of
RAW image may be processed and displayed on a Windows PC using the tools supplied in Common_files.zip.
Mac users may use these tools to perform the same function.
Install IrfanView complete with plugins.
IrfanView is assumed to be installed in folder 'C:\Program Files\irfanView' and named 'i_view32.exe'.
Create a folder on your PC at a location with a pathname that does not contain spaces.
e.g. D:\SDM_DNG
Copy 'process.bat' and 'swap_bytes.exe' to that folder.
When first testing, do not delete the images on the card as they will be changed in the PC version.
From your memory card, copy the single or multiple xxxCANON folders (with the exception of 100CANON) to the PC folder.
Double-click process.bat.
Ignore the message regarding RAW files, that is for 'slit' images and there may not be any in your folders.
The files will be converted to DNG and displayed as a slide-show.
