Here's my problem: I want to use RAW Develop and
I want to save RAWs as .dng and
I want the associated jpgs to be saved at Canon Fine resolution ("Override JPG Quality" OFF). The only way I know of to save the jpgs at Fine quaility is to use the non-exmem version of CHDK. That version does not do the dng to crw conversion on my SX230 (it looks like it starts but then nothing). So I have to save the RAWs in CHDK format to do RAW Develop, but then I don't have a dng file.
The simplest way, for me, would be to have 2 versions of CHDK on the same SDHC card. I'd shoot in the non-exmem version and save as dng and Fine jpg. Then when I wanted to do do RAW Develop I'd restart the camera, with the same SDHC card where all the dng files are, using a "stable" version of CHDK and do the dng to crw conversion and RAW Develop operation. Is this possible?
The only other way I can see is to copy all the dngs to another SDHC card with a stable CHDK version, but that requires a computer, another card, and lots of time and fiddling.
If no dual boot option is there another way? Thanks,
