I've successfully installed the latest stable 1.2 CHDK version for my A4000IS (firmware 1.01b) on a 32GB Patriot LX series SD card. Coming from a dSLR background I am interested in exploring the RAW capabilities of the camera (which actually is my wife's - she's happy to just P&S). I note that the OSD shows an initial RAW count capacity for the card as "110!" which seems a low number for the 32GB card. Is there a simple explanation for this and the significance of the exclamation mark "!"?
And I also note the DNG files generated were a constant 24,769,494 bytes regardless of the exposure parameters, surprisingly large and almost comparable in size to the range of RAW .CR2 files from my full frame 5D Mark III.
Are you sure it's an "!", not an additional digit that's being cut off? With a 32 gb card and roughly 25mb per shot, you should have ~1000 shots. I think the OSD is only formatted for 3 digits.
CHDK DNGs are uncompressed, so they will always be (sensor width * sensor height * sensor bpp)/8 bytes, plus the negligible size of the DNG header and thumbnail. I believe Canon uses lossless compression on their raws.
I don't know about TC specifically, but some programs default to loading large raw files at 50% for performance reasons.
The other question I have relates to the <ALT> button. How does one review a capture on the A4000IS if this button invokes CHDK?
One poster in another thread has mentioned that he had remapped <ALT> to the Help button (can't recall the thread at the moment. How easy is it to do this? I can dust the rust from my Basic but not the C required for the main code.
I wasn't aware of these simple procedures in the CHDK users' manual and the CHDK for Dummies manual. Of course I could have missed it in the big users' manual which I'm still digesting. Else I think it worthwhile to add the tips in the for Dummies manual.
It's Irfanview rather than TC which is just the file manager (late night slip). Good to hear this is a common phenomenon for such viewers (simple editors).
