The exasperating topic again:
Did some shoots in DNG and all are yellowish (yellow and blue). I've used the latest Autobuild version (with black level 128). Adobe Lightroom shows also two main peaks in histogram for yellow and blue.

BTW, bought a small tripod before. It's a so called Gorilla Pad and meant to be used as a travel tripod. And it works! That's a really cool toy!

Noticed that. If I'm open your dng in Adobe Lightroom and your jpg in IrfanView then the jpg will be shown as expected and the dng is blueish oversaturated (and violet). Compare the white wall right beside the window (underneath the red street lamp) or the black BMW. The DNG shows a slightly blue/lila wall and a lila BMW (the owner of the car will not be amused, I'm afraid). Do I have some problems with my software???

Regards!

Because (perhaps ??) those all comes out from jpgs.
IrfanView, in this case, seems to work on the jpg attached to the dng, not on the raw.

The true raw image is also bigger than the jpg (3662x2760 vs 3456x2592) and displays a larger scene (see here http://chdk.setepontos.com/index.php/topic,2838.msg34223.html#msg34223 )

As you say, your images are identical, and this is impossible...
... I think :blink:

I've formatted again the sd card with cardtricks 1.44 and copied the leatest autobuild (2009-05-01). Now it looks okay. The date of previous chdk was 2009-04-30. Without Chdk there wasn't any problems. I've had this error with an older version of chdk too. After fixing it (format-reinstall) no errors for weeks. I've no idea what it was.

Great job to all CHDK developers and to all porters from the Dragon's Lair :D :P :lol
Please keep going this way ! ;)

yep ! dragons use canon cameras 'cause we can "load" CHDK on them O__o'   :blink:

I think it's "hardcoded" or it would be very difficult... btw is it possibile to "disable" compact video mode ? 
( 160*120@15fps max 180 seconds )
It would be nice because it's very easy, as you know, to "roll" unintentionally to this from standard vga@30fps  ::)

Thank you all again ! :)

Thanks, Dragon.

It might be possible to disable compact video mode (or to be more precisely: to replace compact video mode with standard video mode) if you would change according code parts (kbd.c for instance) and build your own specific CHDK-version. You have to adapt generic code parts of CHDK for a very specific function (that reduces general functionality) therefore it would be unlikely that those changes will be flow back in main code (trunk).

If you have questions regarding "Make your own CHDK", don't hesitate to ask for.

BTW: Do you load CHDK from a laser disc? :-)))

Regards!
