He Yarvieh,

glad to hear from you. I would swear like a trooper about that color haze if I would not be so well-mannered...  ;-)))

Regards!

Hi all,

I've had a SX110IS for a while (since December) and have been watching this forum since it started up. I have noticed that those who were finding the color matrix were using a program which reads only 10-bit color raw files.

You might be interested to know that Dave Coffin has finally added in SX110IS support into his dcraw program (http://www.cybercom.net/~dcoffin/dcraw/) program. Since his program fully supports 12-bit images, it may be better than the other since it can output 16-bit images AND can read 12-bit raw files.

Just my 2 cents..

Barring any freakish coincidences, I am having a battery-related issue when using CHDK.  It seems as though battery life has decreased dramatically since I loaded it (by well over 50%).  Has anyone else experienced this issue?

I'm retarded.  A quick search provided all sorts of enlightenment.

I've updated CAM_BLACK_LEVEL to 128 in the trunk.
Don't forget what the H stands for.

You`re wrong in several points here, jpg's use 8 bit per channel not 10, the dng file format supports 12 bit data just fine and we are keeping all 12 bits no data is being converted. The problem is not that there is 'some' difference the dng looks like someone put a heavy blue filter on. Thanks for thinking along with us but though.

We got rid of the blue haze with cam_black_level 128 :)
Still my calibration has little too highly saturated reds (see last page with couple of pictures)...

Im off for 2 weeks now 8)

Hi,  I'm concerned about CHDK for SX110 for long time. I've learned that color matrix  is the obstruction to converting raw files of SX110 by browse this bbs.

I have a idea but I donot know it works or not. we can disassemblers or decompilers the firmwares  and  find out how it deal with raw files, or find out the functions or code segments which deal with raw files.

I'm not a programmer and also have no experience about crack. I donot know this idea is feasible or not.

There are some discussions in forum about this topic. I tried to draw that secret from firmware but gave up at some point. It's not only about finding the color matrix you have to translate it also from some sort of Canon presentation to "real world" numbers.

I'm also encountering the battery drain-out problem, even without CHDK. Batteries are fully loaded and my camera stops very very quickly (after a few shots) and complains "change batteries...".

Ok, I'm off until the end of the week...

Regards!

Lol i tried a little bit more with RAW and I got a 100 same picture with DNG4PS-2.exe from Yariveh!
And it doesnt matter wheather I use Blacklevel 127 or 128 o0

Here are the Pictures:
(All compressed with IrfanView @ JPEG @ 1024x768 @ 90%)
From left to right: Blacklevel 127 JPEG | Blacklevel 127 RAW | Blacklevel 128 JPEG | Blacklevel 128 RAW | Blacklevel 128 JPEG_2 | Blacklevel 128 RAW_2


What that  :o :o :o Why they match 100% ???  :o :o :o NO HAZE OR SOMETHING ELSE  :D :D

Here I uploaded the original files: http://rapidshare.com/files/234417159/128_2.rar

I also tried dcraw but the results are really bad with 127 and 128!

Hi
I usually use FastStone Image Viewer, it works somehow :D
Here your files:
jpg 1600x1200
dng->jpg 1600x1206
