#876 PowerShot G1 can't switch to RAW format

[Anonymous]

I'm trying to use my old Canon PowerShot G1 with gphoto 2.4.10 provided in ubuntu 11.04 .
The camera is detected fine and i can take shots in JPG format, but i can't switch to any imageformat with RAW, i always get this error:

# gphoto2 --set-config /main/settings/imageformat=0
Detected a 'Canon:PowerShot G1'.
Could not change image format

If i try to check shootingmode i get
# gphoto2 --get-config=/main/settings/shootingmode
Detected a 'Canon:PowerShot G1'.
Label: Shooting mode
Type: MENU
Current: Unknown
Choice: 0 AUTO
[...]

If i try to set it to number 4 (M) i don't get errors, but the settings remains in "Unknown" mode
# gphoto2 --set-config /main/settings/shootingmode=4
Detected a 'Canon:PowerShot G1'.
Shooting mode changed

# gphoto2 --get-config=/main/settings/shootingmode
Detected a 'Canon:PowerShot G1'.
Label: Shooting mode
Type: MENU
Current: Unknown
Choice: 0 AUTO
[...]

Something i'm missing or there are some problems with the G1?

Don't know how it happened but apparently i opened the bug twice, is there a way to remove the duplicate?
Sorry.

can you grab debug logfiles for those calls?

add:
--debug --debug-logfile=logfile123.log

debug file for get-config imageformat

[Anonymous]

debug file for get-config shootingformat

[Anonymous]

debug file for set-config imageformat

[Anonymous]

debug file for set-config shootingmode

Done. Attached the log files.

what happens if you do --capture-image right afterwards?

it seems to set something at least, and i think it is some kind of raw setting.

also, what other jpeg modes are available in the G1?

capture image debug log

If i run a --capture-image i get this:
# gphoto2 --capture-image
Detected a 'Canon:PowerShot G1'.
New file is in location /DCIM/100CANON/IMG_0065.JPG on the camera
I checked on the card and there is only the jpg file there, no RAW.

The command was run after a
# gphoto2 --set-config shootingmode=4
# gphoto2 --set-config imageformat=0

As for the other jpeg modes:
# gphoto2 --get-config imageformat
Label: Image Format
Type: MENU
Current: Large Fine JPEG
Choice: 0 RAW
Choice: 1 Small Normal JPEG
Choice: 2 Small Fine JPEG
Choice: 3 Medium Normal JPEG
Choice: 4 Medium Fine JPEG
Choice: 5 Large Normal JPEG
Choice: 6 Large Fine JPEG
Choice: 7 RAW + Small Normal JPEG
Choice: 8 RAW + Small Fine JPEG
Choice: 9 RAW + Medium Normal JPEG
Choice: 10 RAW + Medium Fine JPEG
Choice: 11 RAW + Large Normal JPEG
Choice: 12 RAW + Large Fine JPEG

I can set all the JPEG-only modes fine (no errors), any format which also contains a RAW mode is rejected. From the camera menu i can select only RAW -OR- JPEG

I am quite at loss currently on what the issue is. Lets try setting the values it returns on our failed try:

(We set 4,2,0 ... camera returns 3,2,0 instead ... so lets try to set 3,2,0)

can you build and install:
http://www.lst.de/~mm/libgphoto2-2.4.11.1.tar.bz2

and then select "RAW 2"?

and test e.g.
gphoto2 --set-config imageformat="RAW 2" --capture-image-and-download

It works!
this time the camera dowloaded a RAW file
