is it possible to show ccd + optical temp only?
(by "all" we can see the false sensor value too)

No, it isn't. Otherwise it would require changes in camera independent code parts of CHDK.

Sorry for my inferior knowledge about CHDK - but will it ever be possible to achieve a good-looking DNG format on the SX110IS (i.e. with no flaws as present)? I would love that, as the canon format is quite annoying to work with.

EDIT: So, what I mean is a DNG format written directly when the photo is taken, that would be good enough to be used right away when transfered to my computer.

My post might sound a bit demanding and negative, but I really dig the work that the CHDK crew and people in here have put into the software. It's simply amazing, thanks.

If I had any of the skills needed, I would definately engage into the subject myself. :-)

It might be more helpful if you could explain in what way the current output is not acceptable, and also what tools/workflow are giving these unacceptable results. From what I understand, the color calibration in the latest autobuilds should be pretty good.

Note that in general, the reason to use raw formats (including DNG) is for the flexibility it gives you working with the image after the fact. If you want decent looking images straight from the camera, just shoot jpeg at max quality.

Also note that the SX110 doesn't shoot any "canon format". The .CRW files produced by CHDK are not in canon format. In fact, they are just a dump of the sensor framebuffer, which is hardly a format at all. This is the same data as included in the DNG, but without metadata to tell tools how to interpret it.
Don't forget what the H stands for.

Sorry, I was quite unfocused when I wrote that post.

I am aware what RAW-files are capable of, and the need for them to be "developed" to give a good result. I wasn't aware that the DNG-support on SX110IS had evolved to become betterlooking by standard... I thought I needed a new badpixel.bin/script, but couldn't find that anywhere. Maybe you can point me in some direction?

I am using the old (badpixel.bin) I found, in conjunction with the newest autobuild for SX110IS. Probably not the best possible solution?

Thanks for clearing up the thing about the CRW format in your last paragraph. I can see that the DNG file includes the metadata, which is a pretty useful thing.

As long as you created the badpixel.bin with your camera, it shouldn't need updating. The script can be found in CHDK/SCRIPTS/TEST in the full install zip. It has not changed since it was originally checked in.

@Jespar

VIT40 tried to get a better color calibration as those built in into latest version. Look at here http://chdk.setepontos.com/index.php/topic,390.msg34687.html#msg34687 and the posts before. As far as I have understand he will publish a new color matrix. I don't know when this will happen.
