SD990

[hnikesch]

just formatted my SD card by mistake and had to re-run badpixle script
worked just fine here are the steps
load CHDK to SD card and start CHDK on the camera
start CHDK menu
go to scripting parameters>
load script file (select script file  TEST/badpixle.LUA)
close CHDK manu leave (alt) screen on the LCD
Create badpixle.bin (alt) should be on the lower left of lcd screen
depress shutter release and wait
the camera will flash the blue LED one long flash take an image flash the LED again take 2nd image
takes about 1 min

that should do it
good luck

Thank you, hnikesch.  I still don't have the camera though. Yesterday, I went to a shop to make some testshots.

I brought my own SD card and I thought I could play a little with CHDK on the camera. But I couldn't check the firmware. When I pressed set+disp the firmware didn't show up. I had both the ver.req and vers.req files on the SD card. Can that be a problem? Does anyone have an idea why the firmware check didn't work? That's why I hesitated to load CHDK. But maybe I was just too hasty and forgot to switch to the play mode.

Are there any other known firmwares except 1.00e? A european firmware maybe? The exif data in my testshots only says version 1.00.

Another point is the blurriness in the corners which is quite obvious. Comparing the photos here:
http://www.imaging-resource.com/PRODS/SD990IS/SD990ISA7.HTM
and here:
http://www.dkamera.de/testberichte/canon/digital-ixus-980-is/beispielaufnahmen

- I get the impression that could be too blurry for me. Still, for the small size of the camera, the photos are great and RAW gives a lot opportunities for compensation. When I open the pictures in Adobe Bridge I get all the Camera Raw options for improving the photos.

But compared to the Canon G10, especially concerning the corners, I think I may be happier with the G10.
What do you think?

You are probably pressing the buttons in the wrong sequence. Press and hold set, then press disp. Subsequent presses of disp (still holding set) cycle through various information. I don't remember if you have to start in play mode or not, but it's probably a good idea.

This is the price you pay for a zoom lens in such a small package. You will probably get best results somewhere in the middle of the zoom range, but really my experience with the SD990 is that you only get full resolution in the middle of the image under ideal conditions.

But compared to the Canon G10, especially concerning the corners, I think I may be happier with the G10.
What do you think?

If the the compact package of the SD990 isn't a major factor, go with the G10 (but remember CHDK isn't ported to it yet). The optics will be far less compromised than a compact like the SD990, and you get a real aperture, 5x zoom, native RAW etc.

If image quality was more important than form factor, I'd get the G10 or maybe the SX10. For a pocketable camera that takes decent snapshots, one of the lower end ixus will do almost as well as the SD990 for less money.

Thank you reyalp. Sure, it's the size that sets limits for picture quality, but from my old camera I am used to a better size-to-sharpness ratio.

I've got a Minolta G500 which has a similar size as the SD990. The chipsize is 1/1.8", the focal length is 39 - 117 mm and the pictures are overall sharp.  And the camera has manual aperture and shutter time settings. But Minolta does not build cameras anymore and I need more than 5 megapixels and a wider angle would also be nice. Coming from that camera, the G10 seems a bit too big for me, while on the other hand I wouldn't necessarily need a "spycam"- sized camera. I'd like a camera at the size of the Panasonic Lumix LX-3 but it's focal range is too small for me.

The pictures shot with the G10 have a great sharpness and tolerable noise at low ISO. But they are also a bit odd. It seems that the camera does not apply much correction of the fringing and other things to the JPEGs.
That maybe a reason why it got such a bad critique here:
http://www.dpreview.com/reviews/canong10/page9.asp
So, you are  forced to shoot in RAW and do postprocessing in Photoshop.
I opened the test-JPEG from the above article in Camera Raw and really was able to improve the image substantially.

I love CHDK because it gives the opportunity to get everything from the pictures through RAW and manual settings. From shots at low ISO I can get more quality than the camera's built-in digic processor.

Well, I'm quite clueless in the cameraworld at the moment. Sorry, if this gets a bit off-topic.
Which other current Ixus cameras or small-sized Powershot cameras for which CHDK is available can you recommend?

rather minor thing here, just sorta curious..

anyone played with grids yet, i tried a few but they were all off skew/wrong size screen im guessing, maybe it was something i did, but has anyone else noticed this?

and if so what size is this screen compared to others?

edit:
hrmm I did find this on the first page, i assume this is our screen size? i guess ill tweak around and see if i can create a grid that works using that size vs the 360*240 written on the grid wiki page.

720x240 bitmap display looks better, chdk logo is still messed up, color pallet appears to be different. Canon advertises a "23000 dot display" (720x320 ?) but perhaps this applies to the live view and not the bitmap.

edit:

Yep, found some time tonight.. played around.. turned this one from the wiki:

http://chdk.wikia.com/wiki/Grids#--_Diagonal_Method

Code: [Select]

@title  Diagonal Method
@line 0,0, 269,239, 26
@line 0,239, 269,0, 26
@line 90,0, 359,239, 26
@line 90,239, 359,0, 26

Into

Code: [Select]

@title  Diagonal Method 720*240
@line 0,0, 538,239, 26
@line 0,239, 538,0, 26
@line 180,0, 719,239, 26
@line 180,239, 719,0, 26

and it comes out properly.. hmm I see a few other newer cameras also have this same screen size.. so i suspect this will show up else wheres also with some other conversions if anyone else trys to use the grids.  I guess ill do a few searches on the dev forums and see what i find if not ill convert some more later.

- tweaked battery high/low values. Note, these are stored in cfg, so unless you reset your cfg you won't see any change.

I deleted my CHDK.cfg file, and now it won't come back.  
How do I get my camera to create a new one?

Are there any other known firmwares except 1.00e? A european firmware maybe? The exif data in my testshots only says version 1.00.

No other firmwares are known at this time.

On a SD990 shipped this week I'm seeing a firmware version of 1.01B , so it appears they may have just upped it.

Thanks for letting us know.

If you have this camera, please get a dump and post in the http://chdk.setepontos.com/index.php/board,5.0.html forum. udumper with newdryos should work on this camera.  You can find more information on the wiki http://chdk.wikia.com/wiki/Porting_the_CHDK

You can also try the current 100e port. Occasionally the changes between canon firmwares are small enough that a new CHDK is not needed, although I'd expect that 100 to 101 indicates a bigger change. Running the wrong version probably just crash your camera, but the usual disclaimers apply http://chdk.wikia.com/wiki/FAQ#Q._Can_CHDK_damage_your_camera_.3F

Hopefully will have time in the next few days. Shouldn't be a problem assuming the dumper works fine with this rev.

No dice, causes a crash requiring battery removal.

Hello
I just tried the newest CHDK release on my IXUS 980 1.01B and it just locked up.

I looked briefly for a way to download the firmware, to post it here but didn't find any reasonably understandable How To.

Does any one have the firmware for the IXUS 980, that the CHDK is based on, so I could try out the CHDK ?

[reyalp]

A new port would be needed to support 101B. There is not a firmware dump yet, so porting cannot be started. Even if there was a dump, there is no developer with the camera, although if the differences are minor, a "blind" port isn't out of the question.

See http://chdk.wikia.com/wiki/Porting_the_CHDK for information on how to obtain the dump and http://chdk.wikia.com/wiki/Adding_support_of_a_new_camera for how to make a port once you have that.

You will not find a "downgrader" that will turn your 101B camera into the supported 100e version. The firmware dumps we use for porting are not suitable for re-flashing to the camera.

I have made a dump of the IXUS 980 IS 1.01B firmware, it can be found here http://www.frogkick.dk/projects/photo/CANON_IXUS_980_IS_1.01B_PRIMARY_cam-firm.zip. It would be great if somebody with knowledge of the 1.00E firmware could check how different the two versions are.

I would very much like to be able to take underwater photos in RAW format

Yours!

Hello & welcome, DryDuck !

The dump looks ok, i've added it to the dumps repository...[1]

Purchased a Powershot SD990 today in Toronto.

Firmware: 1-5.0.1.0

Is this yet another firmware version?

[reyalp]

That's not the firmware version.  See
http://chdk.wikia.com/wiki/FAQ#Q._How_can_I_get_the_original_firmware_version_number_of_my_camera.3F

Please note! your camera's firmware version is NOT 1.0.0.0 or 1.0.1.0! It's a number that looks similar to this example: 1.01e. If you get a number like 1.0.1.0, then you did not do it properly and probably the ver.req or vers.req file in the root directory of the inserted SD-card is missing.
