Good morning reyalp,

I just played with the file browser and this one as well is showing me my 200MB FAT16 content, where - on boot - a CHDK folder is created. I deleted it there later using my finder, but after booting the camera it is there again. No contents, just directories. Only 200MB in total, it does not touch the rest of the card. But the camera itself very well recognizes the big card, without modifications it says I have room for 8343 pictures :)

Strange, auto-booting works, CHDK itself starts, but does not find the contents of the FAT32 partition and does not store pictures there.

I have no idea where to go from here, if you need any debugging help for this, let me know.

Oh, and yes, I used the http://mighty-hoernsche.de/ firmware. Tonight I might try my own build (the pipeline works completely including IV/KEY extraction thanks to ewavr), so if you want me to put in some debugging code, let me know.

Need to run to work! Cheers and thanks,
Torben

PS: How do I start in PLAY mode so the camera would detect the FI2 file without me making any modification to the card formatting? I have not found a way to do this.

Mac  ? Possibly a clue there.

Yes, CHDK creates most of it's directory tree if it doesn't exist.

That's very strange. It sounds as if your 200mb partition is marked as fat32 even though it is actually FAT16.

It's something specific to your partition setup. The partition detection and switching code is common to all the CHDK cameras that support multi-partition. I've returned the SD990 to it's rightful owner (hence the flurry of late night commits ;)), and my own camera does not support SDHC, so I'm not sure how much debugging I could do.

Put PS.FI2 on the root of the card.
Power on using the play button.
Choose "firm update" in the menu.

If the FI2 isn't detected, your mac is doing something strange to the copied files. This isn't unheard of. See http://chdk.wikia.com/wiki/FAQ/Mac

reyalp, thanks a lot! It is now working.

I guess the missing step was setting the pid to 1. That is what I haven't known and of course did not do. But on the mac page it is explained.

Sorry for that, really... but I promise I searched - just not specifically for mac :) I should have used my Linux server for the partitioning :)

THANKS A LOT again!

Torben

PS: My partition was displayed as FAT16 (200MB), now I made 4MB only and it became a FAT12, but it is working with FAT12 :)

Great! The instructions for Mac really worked. Now I can use the big partition for storing photos and videos, too. I think the important step is to not include the CHDK folder on the first partition but only on the second, larger one. However, fantastic work, reyalp! Video quality settings are a great new feature, too...

Hey guys! First post here.
My english is very bad.

Thank you for your great work reyalp.I have a few questions.
1.Why the colors from DNG (raw) is very different compare to JPG.Is this the real color that sensor capture or manual color calibration.
2. I think that efl is incorrect chdk shows 35mm but the real  Eq focal lenght is 36-133mm
3.RAW files dont have exif data.
3.DNG vs RAW  what do you guys think.
4.When you quick press the shutter it saves only jpeg.

Manual, see earlier in this thread.

Rounding. It could be adjusted slightly.

3.RAW files dont have exif data.
Raw files are just the data from the sensor. If you want exif data, use DNG, or keep the jpeg.

3.DNG vs RAW  what do you guys think.
You're choice. DNG has almost exactly the same data, except that bad pixels are interpolated over. DNG includes metadata, RAW does not. RAW saves quicker, but few tools know how to deal with CHDK 12 bit raw.

4.When you quick press the shutter it saves only jpeg.
This is a bug.  Similar issues have been seen on other cameras, so I'll see what I can do, but as I mentioned earlier, I don't have the camera any more.

Hi.
I would like to test the RAW files of the SD990/Ixus980.

I want to find out which applications can open the RAW files.
I don't have the camera yet but I would like to buy it if RAW is usable.

Can someone please upload a RAW file or a variety of files?
P.S. I've got a Mac.
Thanks.

Well, CHDK and this forum are really impressive.
Meanwhile, I've found the test CRW  by reyalp and also the DNG that was converted from it on a computer.
Unfortunately I can't open the CRW in any of my Mac programs but the DNG opens in Adobe Bridge.

The DNG has really a better quality than the JPEG. The noise at ISO 80 is ok in my opinion and can stay. Just the blurriness in the edges worries me a bit. Does it get better with higher focal length? The fringing can be fixed quite well in Camera Raw, however.

But, my question is, how can I get the camera to save a DNG?
I must admit that I'm new to CHDK, so I have played a bit with it on an old Ixus 750, and did some reading in the forum. 
But I can't create the badpixel.bin file from CHDK right on the camera.

Can the Ixus 980 do this?
Has anyone got the badpixel.lua script to work on this camera?

Also, as I understand, I can't create the badpixel.bin file on a Mac. Is there a way to do this?

I ran the badpixel.lua on the camera without problems. I don't recall which settings I used, but you should find something in this thread http://chdk.setepontos.com/index.php/topic,156.30.html

Thanks for the info, reyalp.
Just for practicing, I followed the steps described there with the Ixus 750 that I've borrowed.

I can start the script and it tells me to be patient and the two LEDs next to the viewfinder are alternately flashing.
This takes on very long, till the battery is empty I'd guess, and in the end the file is not there.
Maybe this camera can't do that?

This experiment makes me a bit nervous about the Ixus 980.
The crucial point is, that I seem to need the DNG files from the Ixus 980, because CRW wouldn't work for me.
Can't I just use a dummy badpixel.bin file and do the retouching in Photoshop?

From what I've found in the forum, I don't really get an idea about this option.
How would that dummy file exactly look like?
