I still can't get the focus set with your code substituted for mine. instead of crashing it says "started" and does nothing. If I interrupt and start again, then once I had it just page through existing photos, and another time it was toggling through menu settings. Like the "left", "right", "set" is messing with menu settings.


Are you in record or playback mode? The script I posted would only work in record mode.

Hey Phil. I just wanted to say thanks for all your help on the forums. I was going to ask on here why I couldn't get get_tv to work in uBasic on the SX30. I'm using the autobuild from 05APR11 [r1132] and found that that command was crashing my camera. I read in another about the G12 that you mentioned that get_user_tv96 is what you should use. Sure enough I tried it on my SX30 and it worked.

I wanted to use set_tv for bracketing in a simple HDR script. I really don't like the idea of having to use the click command to navigate menus. Especially for something you need done quickly. Even if I wanted to though I would be stuck. I can tell the camera to click left and right. But on the SX30 I need to roll left and right to change the bracketing. How do you do that?

 The only source I have available to me all the time is the UBasic User Guide posted on the main CHDK wika. I'm on a boat for a while and internet is only available a few hours a day and even then is is not guaranteed I can get online. Is there a more up to date guide or way I could look at the available commands on the CHDK I have installed?

Thanks for your time man.

I found an answer to my own questions.

http://chdk.wikia.com/wiki/CHDK_firmware_usage/AllBest#Current_List_of_uBASIC_Operations_and_Commands:

get_tv96
wheel_right
wheel_left

Much more up to date than the uBasic guide/PDF. Still a good manual though. I hope this is in the right post. This is the only SX30 specific post I came across. I hope this helps other CHDK noobs like me. Yea, I said noobs/n00bs/newbs. That just happened :) Now to focus on taking better pictures. This is my first real camera.  Thanks again.

Hi guys, just got my sx30is yesterday and ive been playing with chdk. I got the camera as I wanted a wide angle 24mm and a zoom for astrophotography. So ive relied on chdk for RAW and long shutter speeds which are working great thanks! I was hoping that I could increase the iso. Although the sensor size is small and the noise it going to be high I could use astro software to stack and average frames to counter it.

Ive been testing further and got a few strange results.

1. Interestingly in custom mode C1 the exif shows some very high iso values which I have not set in chdk
(iso 6400 and 12800 both at full resolution 14MP)
CHDK set to iso 8000 (although im not sure this makes a difference here, I saw in the wiki that the sx20 had iso 8000)
CHDK shutter speed set to 24 seconds
CHDK autoiso override disabled
Canon ISO set to autoiso
Photo taken in very dark light

2. Occasionally in manual mode the overrides do not work. I think this happens when pressing the shutter too quickly, and then without changing any settings the next shot would work.

3. Another test, canon shutter speed at 5 seconds and chdk at 1/800. The playback exif info usually shows the 5 seconds although the photo is taken at 1/800, but occasionally it will show the 1/800.

4. Again in manual, canon iso set to 100 while chdk override is set to iso 400. The playback exif info display varies a lot. iso 100, iso 250, iso 320.. with neither chdk or the canon set to auto iso im not sure where these numbers are coming from?

In general, CHDK has never been able to set ISO much (if at all) outside of the factory limits.

Also note that the highest ISOs in canon settings are not actually sensor gain adjustments, but happen elsewhere in the pipeline. E.g. on some cameras raws at ISO 400 are identical to raws at ISO 800, while the jpegs are brighter due to some software trick. Most recent cameras have  "high ISO" mode of some kind which results in a smaller image, indicating some kind of binning process. You can actually use CHDK to force low ISO in this mode to shoot images quickly ;)

Hard to say, but the exif ISOs should not be used to measure the effectiveness of overrides. Compare raw pixel values under constant illumination.

I have not checked this in a while. I was happy with CHDK as is since Beta 9 (except for the start up crash). So, BIG THANK you for the fix.  However, I tested beta-14 aperture override. It does if the selected aperture is between 2.7-8, but not if I want to override it with f11 for example.  Is it  how it is supposed to be (due to physical non-software constraints) or should I be able to stretch it to f11?  I tested it by taking two pictures in M mode of the same thing but one with f8 no-override and one with f11 override (and f16 too) but they were all the same.

While some cameras can use smaller apertures than provided by Canon (the G12 can go to f/11), I'm pretty sure f/8 is the limit with the SX30.

No "Firm update" menu
« Reply #187 on: 03 / May / 2011, 11:12:54 »
I downloaded the latest SX30 version (sx30-100l-0.9.9-1169-full) but I am unable to start CHDK.

I can see the Firmware version fine, but there is no "Firm update".

The hint to "press the playback button twice" doesn't do anything.

The card is a 16gig SDHC class 10. I tried formatting it in one block in FAT32, same thing. I partitionned it in two with a first partition of 100mb formatted in FAT16 and FAT32, same thing. I am working on a Mac.

On every occasion, I can see the firmware (so the vers.req is correctly detected) but no firmware update in sight.

I am at loss. Any ideas?

I have noticed that since the change to CAM_DNG_EXPOSURE_BIAS, programs like Acdsee will no longer preview DNG files. Removing this change brings back the previews.

Will look into it - can you tell me which ACDSee product(s) & version(s) you have tried?
