>I think the DNG colours need quite a bit of tuning to get them as good as the JPG.

You have a good RWA output.
I think you can get automatic the colormatrix value in your case with dng4ps2 program and cal color matrix.see here a screenshot and what must do.

there are also some presets for white balance in, this program use also the jpg from same shoot as compare

Microfunguy

To be able to save in the same directory as jpg I had to modify code at raw.c in raw_savefile() , just bellow

Thanks Phil, that is very useful.

Welcome to 2011 !

(I will be there in thirteen hours)

I've posted a new version here:
https://chdk.setepontos.com/d/5641/1

Changed in this version:
CHDK Raw/DNG is working (but raw develop not working)
Now based on version 1005 trunk
Includes games, calendar

Waldo,

Million thanks for your job.
I got my s95 today 12/31 and tried to install the E version that did not work.
So I downloaded and successfully installed version H.
I don't know about v.8H, but in v.9H the zoom in works and the zoom out doesn't. Autofocus is perfect.
Is it an expected "problem" also reported by others or not?

I wish a good 2011 for you guys.

Thank you,

Only one of the versions will work in your camera. In your case, it is the 100H version.

I don't know about v.8H, but in v.9H the zoom in works and the zoom out doesn't. Autofocus is perfect.

That has not been reported before. Please describe specifically under what conditions that happens.

I start the cam and a message about the firmware appears (CHDK Firmware 'CHDK 0.9.9' Build: Dec 30 2010 18:06:41 Camera: s95 - 100h).

Then it freezes and the optical zoom (I mean the lens) does not move (but the LCD screen is frozen in the last saved shot). So I push the shoot button and the cam turns on. I put it in video mode and starts video recording.

If I start in 28mm and go to 35mm and stops for 3 seconds, the cam does not zoom in again. If I zoom in several times untill 3.8X, it stops there and the zoom out does not work.

The auto focus is OK. It auto focus for long distances if set for landscape, but not for less than 30 cm (for me it is not a problem; the autofocus is OK).

However, if I want start another video or shoot a photo, I can't zoom out unless I turn off the cam.

That is the "problem".

Wish you a good 2011.

Bests,

It sounds like I broke the 100H version. Bummer.

I'll post a fix for the raw develop problem later today.

Please take your time. It is Jan/01. Take a rest.

Anyway, thank you.

It fixes the raw develop issue.

I download S95 sources and look at

stubs_entry.s

file.

the address of strcat and strncpy is same, which is wrong.

NSTUB(strcat, 0xff81402c)
// Best match: 56%
NSTUB(strchr, 0xff8140b4)
NSTUB(strcmp, 0xff82069c)
NSTUB(strcpy, 0xff820684)
NSTUB(strftime, 0xff8b8660)
// Best match: 79%
NSTUB(strlen, 0xff8206bc)
NSTUB(strncmp, 0xff81406😎
// Best match: 73%
NSTUB(strncpy, 0xff81402c)
// Best match: 71%

Here i have open a thread about this, seem not so easy to add a correct strcat func in libc.a

In CHDK, the addresses in stubs_entry.s are automatically generated and may have errors. Corrections to this are in stubs_entry_2.s. You also need to look at that file.

Jop

I don't know if someone could put all old versions of the binaries (E and G) available here or in other site. If someone has a problem or want see the differences between versions could easily see and download them as well the sources.

I wish someday I can help others as you guys do...

thanks now i understand more how that work, here the S95 Port have a address, so the function is in.But i need find it in IX 1000 asm

Hey guys,

I found something very interesting (sorry if it was already reported). It is not about script but ...
If you put in video mode (AF or manual focus) and start a video, you can zoom in and out with the control ring up to 3.8X. But if you use the zoom lever, you will be unable to zoom out again with the control ring.
To be able to zoom out or in again you don't need turn off the cam, just press the playback button (the blue arrowhead) and restart another video.

(I am using v.H 10; v. E 10 seem to work fine for others)

There was a patch made for that on 100E. I'll check that on the 100H.

I posted a new version that should fix the video zoom issue

In both these cameras the function is located just before the string "GetCameraObjectTmpPath ERROR" in the firmware.

That was easy, 0xFF95E84C for both 100E and 100H.

For my purpose, I have used it in the regular get_target_directory_num() to return just the number.

@Waldo

As a matter of interest, does ubasic_set_led(2,100) turn-on the AF led ?

What colour are led's 0, 1 and 3 ?

Jop

@Waldo,

IT WORKS. Thank you a lot. Now the zoom in and the zoom out are working. The digital zoom also.
I am gonna post some videos on YT and give you the credits.

The function when called from C is void camera_set_led(int, int, int). From ubasic it is set_led a b.
0=green / 1=red / 2 = AF

Sorry about this stupid question, there is something I don´t exactly understand reading these threads: Is it possible to zoom (no digital zoom, "mechanical" zoom) AND having a working autofocus while filming with this CHDK?
If yes, I will buy tomorrow a S95.
Thanks for an answer and forgive my terrible english...
