RAW and DNG formats

Hello there!

Do any of you have successfully opened raw files from the Canon SX20 with CHDK?

Raw fles is one of the main reasons why I'm trying CHDK.
I took some pictures, got the CRW files but... I cannot open them in Photoshop CS5.

So I tried to set DNG format on the camera but an Error message came on saying some file .lua was missing...

Please, help!   :(

Please read the stickies in the raw forum. Short version: CHDK raw is not a format, it's just a copy of the sensor data. It is not related to the canon raw formats that use the CRW or CR2 extensions, so most tools don't understand it. Tools that support CHDK raw frequently need to be updated to support new cameras.

For DNG, read the error message carefully. It tells you that you must run the lua script. See also http://chdk.setepontos.com/index.php/topic,2468.msg30870.html#msg30870
Don't forget what the H stands for.
