CHDK RAW is not a standard format.  In fact,  its not any format - its just a raw dump of the sensor data.  So standard software tools usually will not be able to read it.   Convert the RAW to DNG by selecting DNG in the CHDK RAW menus.  The DNG format is compatible with most software.

Hi thanks , so CHDK raw Is different from Canon's Raw?This was not perviously clear! Does the DNG format still have the RAW 's advantage in that nothing is degraded in editing "ie rotating" ?
Thanks Brian Wildman

People often have this difficulty.  Sometimes you just have to read the documentation.

Thanks , I followed one of your links to find that Google Piccaso seem to enable editing.

I ,probably like a lot of new users find all this different format thing a bit confusing and daunting
Thanks for taking the time to help me
