I have amended the raw.c as suggested by richlock and recompiled using the CHDK-Shell version 3.
No change! still getting 0 byte CRW on the SD.
I have assumed i can simply make changes to the raw.c as suggested and recompile. Was there anything else I needed to do?
BTW any chance of some one pm me with the SX110 IS keys? As the dumping skills are absent at this time!!!
thanks all for help to date, this is very exciting what I can now do with my camera! BUt no RAW is preventing me getting into some HDR fun!
Further help appreciated
