The only thing i know is the CHDK loaded successfully and the camera do Saves RAW image.
Thanks, that's all I need to know. The port should behave identical to the 101a port which means RAW is very likely OK (if you shoot DNGs, it should be easy to test).

@nafraf

If you're reading this, can you write some details about the 102e port? If that is also based on the 101a port, we could just add 102d and 102e and enable them in autobuild.
Hi, I attached the JPG and DNG/Raw Images Below from the testbuild

Looks okay, thanks. I have committed the code.

If you have time, could you install the official release from this page, and check if it's working OK?

:'( I think I forgot to commit 102e port.
The port is based on 101a, it uses the same code_gen.txt.
Thanks for this. Unfortunately, the included code_gen.txt is not the same as the official one, but I was able to use it to correct my 102d version.
The bigger problem is that the rest is not compatible with current trunk, so I'd better not risk to make the required changes blindly.

I just tried, it seems everything is working perfectly  :)

just the RAW file color need to be calibrated when edit ( i mean the raw file kind of green-ish without edit)

--edit: the manual flash power(min/med/high) will not fire when the flash setting is turned off (Program mode), is this normal ?

That could be difficult. If you'd like to try:
- read this page: http://chdk.wikia.com/wiki/DNG4PS-2/Calibration
- get my hacked DNG4PS-2 version (AFAIK the official one doesn't support the GRBG matrix)
- create a profile for your cam (settings -> camera options -> select an existing profile -> press "copy..." -> fix camera profile data (name and everything) -> OK)
- go back to the newly created ixus1000 profile and press the "calc color matrix" button under "color matrix #1", this will start the calibration GUI

Tried it on one of my cams, it does the same so I guess it's normal.

When i select the RAW file, it says "Selected RAW file not suitable "  :( , tried DNG and CRW

edit : -- nevermind ---  lets just forget about it, seems too complicated ....

Don't give up yet.
1) You need to have the CRW and JPEG pair in the same directory.
2) The camera's name in the profile is important: it needs to match what you find in the JPEG exif data. In your case, it's "Canon IXUS 1000HS" (without the quotes).

Hmm, I currently have
CRW_5444.CRW
IMG_5444.JPG
in the same Directory, the camera name is set to "Canon IXUS 1000HS" as JPG exif data.
tried short name put the same also give ERROR Opening Raw ...  :-[
edit RAW exif also display  "Canon IXUS 1000HS" from DNG
the CRW Raw does not have EXIF data (?)

I'm not sure if you have actually created a camera profile inside DNG4PS-2. I have attached one made by me (I had an old raw+jpg pair from this model). It's not perfect, color matrix data is from a different cam and I have left the whole area as 'active zone'.
The profile can be imported: settings -> camera options -> import cam. You may need to explicitly select this profile on the 'camera types' page (3816x2784).
If you do have a profile, delete it before importing the attached one.

That's right: the CHDK RAW (CRW, CR2) file is pure sensor data, nothing else.

Im getting
Code: [Select]
POOR RESULTS. CAN'T CONTINUE!!!

REQUIRES MIN <= 15.0%.
BEST RESULTS FROM G=2.02000, min(E)=19.2%maybe i did something wrong..  ::)
Using yr profile to convert CRW to DNG, the color seems to be calibrated.
btw are we able to "export" this profile to adobe photoshop ? or somewhat "save" the profile to the camera, so when we take DNG file so the color is calibrated? (sorry if this question is asked before)

Thanks

Yeah, that's what most people using newer cameras usually get. May depend on the kind of the monitor you're shooting. There are some words of advice on the wiki page too (using the brightness slider, etc.).

You're saying that

you're getting green-looking raw in the software you're using (Photoshop).
The DNG you uploaded earlier appears relatively fine for me when opened in Irfanview or Raw Therapee. Could it be that Apple Adobe products parse the DNG metadata differently?

Can you upload a screenshot that shows the difference between the camera JPEG and the uncorrected DNG as it shows in Photoshop?

For DNGs converted by DNG4PS-2, I can confirm that the color matrix data from my profile does produce a good looking image while the current CHDK color matrix produces an image with strong green cast. These converted DNGs however lack the white balance data that is recorded in CHDK DNGs.

Note that the ixus1000 CHDK color matrix has relatively recently been changed. I have no idea if it is supposed be correct.

edit:
it's the other 'A' company
