I don't want RAW files

Hi everyone!!
I've been trying to do a timelapse, but my 4gb sdcard is fulled out in a short period of time due to the ".CRW" files stored in the 100CANON directory.

I already went to "RAW parameters" and disabled the "save RAW" option, but .CRW files are still being generated, and being almost 20 mbs each, my sdcard can't last too long.

So, how do I completely disable RAW generation? Thanks!

PS: If it helps, the camera is a SX220 HS

If you go back to the RAW menu, is it enabled again ?

No, it's still disabled. Even if I turn the camera off and then on again it stays disabled.

Could you remove CHDK config file (CCHDK.CFG or something similar in /CHDK directory on SD card). If you want you can backup it first.

Then you can try to disable RAW saving and check, what's going on. Nevertheless, the way your camera behaves is strange...

alejoar - any chance that you accidentally hit the CHDK RAW shortcut ?

On the SX130 this may be the [+/-] button...

If so, you'll see the RAW (or DNG, if enabled) indicator on the screen...

On my G10, when you hit the CHDK RAW shortcut,  it enables RAW such that RAW will show up as selected in the RAW menu.   He said that menu item is not selected so it does not seem likely the shortcut key would be the problem ?

.. but only in shooting mode and only if you have enabled that indicator in the  OSD Parameters -> RAW -> Show Raw State menu item.

Hey, thank you all for the help, you are awesome people!

Ok, last night I did what outslider said: I deleted the cfg file and the raw files were not generated the first time I ran the script (timelapse).

But here's the weird thing: the second time I ran the script the raw files were generated again. It's like the script somewhere enables RAW generation and from the second time I run it and on it stays enabled (even though the menu indicates it is disabled).

I've been searching for the exact script I'm using in my camera so you guys can take a look, but I can't find it now (I'm at work and my camera is at home). All I remember is it was a LUA script mented for energy saving. Also, I modified it to turn off the backlight of my camera after every shot as it didn't do that formerly.

I gave the script a quick look but couldn't find anything shady. I'm not that good scripting anyways.. I'll post it tonight. Thanks!

PS: I know my writing is messy, sorry, not native speaker here.

It's possible for a script to enable raw, you should look for the set_raw command. This should show up in the menu though, and it's hard to see how it would start saving the second time around...

Hey, here's the script. I only added the sleep and set_backlight after shoot at the end, everything else is untouched. There's no set_raw.. I don't know what else could be causing this. If nobody finds anything I'll guess I'll stick to deleting the cfg file everytime :P

Thanks!
Code: [Select]
--[[
Author: Fraser McCrossan
Modification for SX100 IS: Anar Ibragimoff

An accurate intervalometer script, with pre-focus and screen power off options.

Features:
 - input is frame interval plus total desired run-time (or "endless")
 - displays frame count, frame total and remaining time after each frame
   (in endless mode, displays frame count and elapsed time)
 - honours the "Print" button during frame delays (so you can
   get it running then turn off the display to save power)
 - can turn off the display a given number of frames after starting
   (might take a couple of frames longer to cycle to correct mode)
 - can pre-focus before starting then go to manual focus mode
 - use SET button to exit

Additional notes:
 -  To use "display off" feature, you need to configure your camera
    to turn display off on "Print" button (in standard camera's menu)
 -  For additional power save I'd recommend to turn off preview after shoots (in standard camera's menu)


 See bottom of script for main loop.
