Thanks.
I guess
16922 MY_COLORS should be SCN_COLOR_SWAP, since the canon page has no specific "my colors" mode.
2595 VIDEO_MY_COLORS should probably be VIDEO_COLOR_SWAP, again assuming no distinct "my colors" mode.
Canons spec page unfortunately only lists the video resolution/frame rate, not the modes.

A640 should be the same, since canon uses the same manual for both.

The night modes are confusing. The CHDK mode list has SCN_NIGHT and SCN_NIGHT1 but it's not clear what they refer to. I guess I need to grep the code and see if I can figure out why 1 was created. For non scn modes, there is NIGHT and NIGHT_SNAPSHOT

The canon manual isn't much help in this respect

Quote

Night scene
allows you to capture human subject against the backdrop of an evening sky or night scene flash is directed at the person and shutter speed is slow...

Quote

Night snapshot
Allows you to take snapshots of people against twilight or night backgrounds by reducing the effeccts of camera shake...

ok then....

Oh and thank you canon for "securing" your PDF manuals so adobe reader won't let me copy/paste quotes

What we would really like to have one constant for modes that are functionally equivalent, regardless of whether they fall under the "SCN" category or not, but that may be beyond our reach.

Some we can probably safely guess
LANDSCAPE/PORTRAIT/INDOOR/STITCH/SPORT must refer the same thing whether they get a position on the mode dial or end up in the scen menu on a particular camera, right ?

I also suspect that some of the existing CHDK mode constants refer to the same thing, e.g. GRASS/FOLIAGE and CHILD/KIDS_PETS.

No need for the full log BTW. Modes that aren't in the "normal" test will always fail, because the script uses CHDK mode numbers, and it only has canon numbers for ones in the modemap. OTOH, I guess it does give you a list of all the modes CHDK knows about.

Just catching on to this thread. Not sure if you caught my posting here (http://chdk.setepontos.com/index.php/topic,4479.0.html) but I had implemented the set_capture_mode_type on my SX10, and tested various modes based on what I had found previously in the firmware to find several working modes that were not part of the regular available modes.
These fell into 4 categories:
1) Named modes that are part of normal camera operation (ie, ones on the mode dial)
2) Named modes that are not part of the camera operation, but work as advertised on cameras they are available on (e.g., fast shutter, slow shutter, digital zoom, etc.)
3) Named modes that do nothing (e.g. ISO6400, Creative Light Effects)
4) Unnamed modes that do something, but I never really tested fully to figure out what (e.g., there were additional mode numbers that did colour swap and colour accent, some that did an extended shutter speed by default, etc.)

On top of this, setting to some modes between the working (or at least settable) modes, would lock up the camera (I didn't fully test the extent of working/non working modes).
One of the interesting things I also found was that I could set custom to one of the inaccessable modes (I currently have it set on Digital Macro which is normally available on the SX10).

This may be of some help in the development here. From what I've seen, it would seem that (all?) modes are (may be?) present and settable in all cameras (at least of the same OS type) just not enabled or fully functional, and that perhaps all cameras (of the same OS) share the mode numbers.

One really curious outcome is the presence of the ISO6400 mode. It doesn't do anything notable, but the only record I have seen of it elsewhere is as a mode available on certain DSLRs. I'm wondering whether this may indicate the the DSLRs share a lot of software portions with the P&S cameras which may be positive news toward DSLR CHDK development.

That is interesting, you were able to set modes not in the modelist ewavr found. I'm a bit surprised by this, because there appears to be a function that checks the list and reports an error for modes not in the list (but it's just log, not assert, so maybe it's just ignored)

I don't see any general way to reliably determine which of these undocumented modes is fully functional, so it is just something for people to experiment with and note what works and doesn't.

Where are you getting the names and numbers from ? Looking at the sx10 dump, the event name "ModeDialToKidsAndPets" is the only result I get searching for "kids" for example. It seems to me that the event table lists events for pretty much every camera that exists at a given time.

From what I've seen of the DSLR dumps, this is absolutely not the case. I suspect they are done by two different development teams, using completely different codebases for the non OS portions of the firmware.

This was a number of weeks ago before it was fully implemented. I had noticed the function showed up in the trunk but was commented out, so I just reinstated it and added a lua registration so I could script it.

Yes. I only found it through experimentation really. What happened was I was doing some testing with ISO3200 mode so I did a search for its mode number and found a pair of functions, one that converts a mode number to an index(?) number, and one that converts the index to a mode. Basically I steeped throught the functions and collected all the mode numbers referenced and tested them individually. When testing, the Kids&Pets mode actually gave me a mode icon in record. For all the other modes there was no icon, but in playback and in the exif there was a corresponding icon/mode name. Was really all just a shot in the dark.

Perhaps. It's just curious that there actually is an ISO6400 mode referenced (you can find this in the strings as well) but it doesn't work, and the only cameras that currently have an ISO6400 mode are DSLRs from what I've seen.

If you happen to still have the addresses of the functions, please post them.

I'm sure "ISO6400" for P&S is in the works, since competitors are doing it. It's also not surprising for them to have allocated constants for it, I would guess that the code that interprets/displays jpg understands pretty much all possible values of things like shutter speed, ISO, aperture, even if it's not present on that particular camera (I have a sneaking suspicion that's where the ISO6400 string comes from.)

I don't have my original work here with me, but from a quick search they approximately start at FF88754C & FFAF77A0 (SX10 101A). An easy search method is to look for a reference to 0x401E which is the ISO6400 mode.

The CHDK mode list has SCN_NIGHT and SCN_NIGHT1 but it's not clear what they refer to. I guess I need to grep the code and see if I can figure out why 1 was created. For non scn modes, there is NIGHT and NIGHT_SNAPSHOT

NIGHT1 is only used on G7, which has both "night scene" and "night snapshot" under the SCN menu.

A warning to anyone using the CHDK mode names/numbers in script: I'm going to take this opportunity to clean them up before they are in wide use, so consider them preliminary and subject to change for now.

set_capture_mode_canon() works in the A590IS.

When I use:

set_capture_mode_canon(8225)

I get a mode where the cam sets TV/AV by itself. The mode icon where it usually shows M, TV, AV, AUTO, etc... is just an empty gray box so I'm not sure what mode it is. It doesn't look like any of the other modes the the cam comes with.

In this mode the A590IS picks TV/AV like in Auto but you can change ISO, AWB, etc.. or any thing in the Func.Set menu.
It took some pictures without a problem too.

Cool

set_capture_mode_canon(8225)

This value isn't in the a590 canon mode list. Try some other random value (say 8123) and see if it behaves the same.

t looks like the a590 CHDK mode map has many errors. If you can run the setmode.lua test script in batch mode, and post the log, that would be helpful.

If you want to help even more, you can follow the instructions in http://chdk.setepontos.com/index.php/topic,3828.msg35931.html#msg35931 to record the canon mode value for each available camera mode. Note that because the a590 is a propset 2 camera, you'll need to watch prop 49 instead of 0 (so go to page 4 in the propcase view).

I can't find the canon mode list for a570 at all. By reference to other firmware, I would expect the function that returns it to be FFEE5EC0, called from FFEE26E4 (in 100e).
