1.) Somewhere in the manual there is told, you can only create dng-files when setting the cam to jpg, when setting to raw the dng won´t work.
Quote1.) Somewhere in the manual there is told, you can only create dng-files when setting the cam to jpg, when setting to raw the dng won´t work. CHDK doesn't know or care about Canon RAW at all. The confusion may be that CHDK also supports "CHDK raw" which is just a sensor dump but is usually saved with a CR2 or CRW extension. You cannot save this at the same time as DNG.
CHDK and Canon exif values may not be reporting the same thing, (you can also see the shutter and aperture are slightly different). For ISO, Canon uses two different values "real" and "market" as discussed here: http://chdk.wikia.com/wiki/CHDK_User_Manual#Override_ISO_valueThat doesn't completely solve the puzzle though, because in general CHDK should work entirely in "real" values, so a minimum of 100 should result in 100 in the CHDK case ("real") and something a bit higher in the Canon case ("market")
At least it is not only a reporting thing, because the dng-files are darker (lower iso) than the canon-raws.
I'm finding that my CHDK 1.1 DNG's give wrong exposure time, they are limited to 15s where they are really 240s or more. Maybe it has to do with DNG 1.1 or 1.3.
Also my DNG's don't decode in special ISO3200 mode.
